Product Description

Product Description of Cylindrical Roller

Cylindrical rollers are the core rolling elements of cylindrical roller bearings. They possess a precision cylindrical structure and achieve force and motion conversion through linear contact with the bearing's inner and outer ring raceways.

Arrangement: Parallel distribution within the bearing effectively prevents tilting and friction, reducing rotational torque increments.

Mating Structure: Different rib designs are available depending on the bearing type. For example, in double-row bearings, a three-rib design is used with the inner ring, while a ribless outer ring design allows for bidirectional axial displacement, enabling precise adjustment of clearance and preload.

Processing

Cylindrical Roller Machining Process

Base Material: Made of high-purity alloy bearing steel such as GCr15, this bearing undergoes a full-body quenching heat treatment to achieve a uniform martensitic structure, ensuring high strength, wear resistance, and fatigue resistance.

Surface Treatment: Through precision grinding and superfinishing, roller surface roughness is kept to an extremely low level, reducing raceway wear and extending bearing life.

Special Adaptation: For extreme environmental requirements, customized solutions are available, including stainless steel (for food and medical applications) and high-temperature alloys (for metallurgy applications), withstanding operating temperatures from -50°C to high temperatures.
