Product Description
IKO Shell Type Needle Roller Bearings are lightweight bearings with large load ratings. They employ a shell type outer ring made from a thin special-steel plate which is accurately drawn, carburized and quenched, thus providing the lowest sectional height among the Needle Roller Bearings. There are two types of bearings available in this series; the caged type and the full complement type. The appropriate type can be selected according to the operating conditions. The caged type has a structure in which the needle rollers are accurately guided by the cage and thrust rings. It is useful for applications at high-speed rotation. The full complement type needle roller bearing, on the other hand, is suitable for heavy-load applications at low-speed rotation. Since these bearings are press-fitted into the housing, no axial positioning fixtures are required. They are ideal for use in mass-produced articles that require economy, and have a wide variety of applications.
Exceptional Durability and PerformanceWith a shell hardness of 58-64 HRC and ground, polished surfaces, these needle roller bearings deliver excellent durability and reliability. They can withstand demanding environments and high radial loads, making them ideal for automotive, industrial, and printing machinery applications. Their lightweight, thin-walled structure ensures efficient space utilization without compromising performance.
Versatile Application and Press Fit MountingDesigned for versatility, these bearings support a wide range of applications. Whether youre fitting them into automotive systems, manufacturing equipment, or printing machines, the press-fit mounting allows for simple, secure installation. A choice of cage materials (polyamide or steel) and optional sealing ensures compatibility with diverse lubrication and operational requirements.
FAQs of Shell Type Needle Roller Bearings:
Q: How are shell type needle roller bearings installed in machinery?
A: These bearings utilize a press-fit mounting type, enabling secure and straightforward installation into housings without the need for special tools. The thin-walled shell design allows for easy fitting, even into compact spaces commonly found in automotive and industrial equipment.
Q: What benefits do shell type needle roller bearings offer for high-speed applications?
A: With limiting speeds up to 32,000 rpm and a high radial load capacity, these bearings efficiently handle demanding, high-speed operations. Their ground and polished surfaces minimize friction, while quality material and hardness ensure long service lifeeven in temperature ranges from -20C to 120C.
Q: When should I choose polyamide or steel cages for these bearings?
A: Polyamide cages are recommended where lightweight, quiet operation is preferred, and moderate temperatures are expected. Steel cages offer increased strength and durability, making them suitable for applications involving higher loads, elevated temperatures, or corrosive environments.
Q: Where can these bearings be used effectively?
A: Shell type needle roller bearings are ideal for use in automotive assemblies, industrial machinery, and printing machines, especially where space constraints require thin-walled, lightweight bearing solutions. They are widely supplied, traded, and manufactured across India.
Q: What processes are used to achieve the precision and hardness of these bearings?
A: The bearings are manufactured from high-grade bearing steel and undergo precision grinding and polishing to meet ISO standards. Heat treatment imparts surface hardness of 58-64 HRC, ensuring the products longevity and performance in demanding conditions.
Q: How should these bearings be lubricated and maintained during operation?
A: Depending on your applications speed and load, you can use either grease or oil for lubrication. Proper maintenance involves regular inspection and replenishment of lubricant, and optional seals can be selected to keep contaminants out and extend service life.
