Single row cylindrical roller bearings without inner or outer rings type
Cylindrical roller bearings have rollers that provide a modified line contact with the cylindrical inner or outer ring raceways, while the rollers are guided by ground ribs on either the inner or outer ring. 
We offer premium cylindrical roller bearings under the LYNB brand names. Most LYNB cylindrical roller bearings feature case-carburized components. Rings and rollers are made from case-hardened alloy steel of “Bearing Quality” to provide superior fatigue life and reliability. Precise control of heat treatment, dimensions, and surface finish of the components further contribute to reliable bearing performance. So whether you’re looking for China-made, case-carburized inch series cylindrical, or a metric series through-hardened variety, LYNB has you covered with a proper fit to your application. Premium steels and heat treatments are also available for applications requiring extended life and high reliability.
▲   The design’s of all these single row cylindrical roller bearings w are based on standard structures; LYNB can design and manufacture many other similar structures in accordance to the special and particular requirements of their customers’. If our customer’s have specific requests then the customer should identify the structure, and mounting dimensions that are required.
