2. Rodamientos de alta precisión: el corazón de la maquinaria rotativa
High precision bearings rely entirely on high-quality rolling elements. Deep groove ball bearings, angular contact bearings, cylindrical roller bearings, and tapered roller bearings all use steel balls or rollers as their load-carrying interface. In high precision bearings, rolling elements determine rotational accuracy, speed capability, and service life.
JSW provides high precision steel balls, rollers, and needles used for various bearing productions. Chrome steel is the most used material for this application, demonstrating high hardness, resistance to deformation, and excellent wear characteristics for maximum strength and service life. This material is known as 52100 steel in the US, 100Cr6 in Europe, SUJ2 in Japan, and GCr15 in China. Bearing balls are manufactured from the highest quality material and provided through-hardened.
JSW manufactures bearing-grade steel balls (G10-G100) and rollers with tight tolerances, suitable for rolling elements applications such as machine tool spindles, electric motors, and robotics. Our rolling elements are compatible with major bearing standards including ISO 3290 y ASTM F2215.
3. Fabricación de ruedas giratorias: elementos rodantes para la movilidad
Castors used on furniture, medical equipment, and industrial carts depend on rolling elements for smooth movement. Caster applications typically use hardened steel balls or cylindrical rollers in the swivel head and wheel bearings. Rolling elements in caster production must resist shock loads, dirt, and moisture.
JSW provides AISI 1015 low carbon steel, AISI 420 stainless steel balls, and POM balls for the caster production industry. Steel balls are used in the main load bearing of the caster—the row of steel balls or rollers that swivels the horn base in relation to the mounting plate of a swivel caster, counteracting direct thrust. Balls manufactured in low carbon steel are adapted for low load and walking speed applications, while stainless steel balls are suitable for high speed and abusive applications such as side-impact loading and heavy loads.
JSW supplies case-hardened steel balls and stainless steel rollers for caster wheels, ensuring quiet operation and long service life. Balls supplied by JSW can be mounted on casters of various sizes, assuring long life and dependability of your products. Heavy-duty casters for warehouse equipment may use larger cylindrical rollers to support high static loads.
4. Guías de movimiento lineal: elementos rodantes de precisión para un desplazamiento suave
Linear motion guide systems use recirculating steel balls or rollers to achieve low-friction, high-accuracy linear movement. In these rolling elements applications, rolling elements circulate through closed loops within the carriage, providing smooth translation with minimal wear. Linear motion guides are essential for CNC machine tools, robotic arms, pick-and-place systems, and measuring instruments.
JSW provides high-precision steel balls and rollers for linear motion guides. An LM guide provides linear motion by recirculating rolling elements between a profiled rail and a bearing block. Its internal balls or rollers minimize friction, allowing the block to travel along the rail smoothly. The coefficient of friction of an LM guide is only 1/50 compared to a traditional slide.
The common sizes of steel balls used in linear guides are 1/8″, 3/16″, 1/4″, 5/16″, 15/32″ and rollers: 3×2.8, 3.22×4, 4.53×5.5, and more. JSW manufactures balls and rollers of standard size or according to your drawings, providing products with high precision and great moving accuracy. Properly selected rolling elements eliminate stick-slip and ensure positional repeatability.
5. Envases para productos de higiene personal y cosméticos: elementos rodantes higiénicos
Packaging machinery for personal care and cosmetic products requires rolling elements that operate in clean, sometimes corrosive environments. Filling machines, capping stations, labeling systems, and conveyor belts use stainless steel balls and plastic rollers. In these applications, rolling elements must resist washdown chemicals, humidity, and occasional contact with cosmetic ingredients.
JSW provides the cosmetic and personal care industry with highly technical and well-tested balls, including AISI 302, AISI 304, and AISI 304-L unhardened austenitic stainless steel balls which display good mechanical characteristics, toughness, and corrosion resistance. AISI 304L provides lower carbon content, while AISI 302 offers better mechanical characteristics. All balls are provided annealed and passivated.
The most common cosmetic rolling elements applications include:
- Agitator balls for eyeliner
- Stainless steel balls as nail polish mixing beads
- Balls in trigger sprayers, finger and lotion pumps, soap dispensers, micro-valves for atomizers
- Balls as check valve balls
- Balls for aerosol pumps and valves
- Balls for roll-on lipsticks and lip moisturizers
JSW offers 304 and 316 stainless steel balls, as well as engineering plastic balls (polyurethane, POM) that are non-corrosive and non-magnetic. These rolling elements ensure smooth, reliable operation of high-speed packaging lines producing shampoo, lotion, lipstick, and other personal care items.
6. Punta de bolígrafo: elementos rodantes de precisión en miniatura
One of the most ubiquitous yet overlooked rolling elements applications is the ball pen point. The tiny tungsten carbide or stainless steel ball at the tip of a ballpoint pen is a precision rolling element. In this application, the steel ball rotates freely in its socket, picking up ink and transferring it evenly onto paper.
JSW manufactures miniature steel balls down to 0.5 mm diameter, with exceptional sphericity and surface finish. These balls are also used in rollerball pens, cosmetic applicators, and certain medical spray devices. Despite their small size, these rolling elements require the same rigorous quality control as industrial bearings.
7. Aplicaciones en energía eólica: elementos rodantes de alta resistencia para energías renovables
Wind turbines rely on large rolling elements in their main shaft bearings, yaw bearings, and pitch bearings. These rolling elements applications demand extremely high load capacity, fatigue resistance, and long service life in harsh outdoor environments.
JSW provides large diameter high carbon chrome steel balls for the wind power industry. The steel ball for windmill bearing is generally in the range of Φ 45-80mm, used for yaw bearings and pitch bearings. Windmill bearings are required to last more than 20 years as the working environment is tough and maintenance costs are very high. Therefore, windmill bearings have strict quality requirements on steel balls.
High carbon chromium steel 100CrMn6 and 100CrMnSi6-4 refer to the high carbon alloy steel with 1.30-1.65% chromium, which have high stress fatigue strength, good size stability, and abrasion resistance. These balls are designed to be more durable than conventional chrome steel balls. In wind power applications, cylindrical rollers and spherical rollers support multi-megawatt rotors under variable wind loads.
JSW supplies large-diameter cylindrical rollers and steel balls (often >50 mm) that meet the strict cleanliness and hardness requirements of wind turbine bearing manufacturers. Properly manufactured rolling elements contribute to reduced downtime and lower maintenance costs for renewable energy installations.
8. Transmisión universal: elementos rodantes en los sistemas de transmisión
Universal drive lines—found in trucks, tractors, off-highway vehicles, and industrial equipment—use rolling elements in universal joints, slip splines, and centre bearings. Needle rollers are particularly common in cardan joints, where they allow angular misalignment while transmitting torque.
JSW has supplied rolling elements for the universal drive line for a long time. We provide needle rollers for universal joints and tripod joints, and steel balls for ball-cage CV joints (constant-velocity joints). In order to transmit torque and direction reliably, the CV drive shaft and universal cardan shaft must be able to bear continuous vibration and impact during high-speed operation, with low noise and long service life to resist fatigue wear. Therefore, the needles and balls inside the joint must have high quality and performance to meet these strict requirements.
Our matching needles and balls are manufactured with chrome steel 100Cr6/GCr15, through stable heat treatment and precision grinding processes. Quality level is always strictly controlled based on standard DIN 5402-1/3, ISO 3290, or higher requirements. In universal drive line applications, rolling elements must withstand high torque, impact loads, and contamination from road debris. JSW manufactures heat-treated needle rollers (diameter as small as 1 mm) and cylindrical rollers with case hardness up to 60 HRC. These components ensure smooth power transmission and extended drivetrain life. The competitive price and good quality have brought us good reputation and trust from all our customers.
