Product Description

Double Row Self Aligning Roller Bearing 22318CA Brass Cage Bearing

22318CA Self-Aligning Roller Bearing With Brass Cage For Heavy Machinery Engineered to meet the exacting demands of diverse industrial applications, this bearing combines precision engineering with robust performance for modern machinery requirements.

Design and Structure

Inner Ring and Outer Ring The inner ring features a precisely machined double-row raceway for 90mm shaft diameter, ensuring efficient force transfer and minimal slippage. The outer ring's spherical raceway provides self-aligning capability, accommodating misalignments of 1°-2.5° between shaft and housing.

Rolling Elements and Cage Double-row barrel-shaped rollers interact with the spherical raceway to handle radial and bidirectional axial loads. The brass cage (CA designation) maintains roller arrangement and provides excellent thermal conductivity for medium to high-speed applications up to 150°C.

Sealing Structure Available with contact seals (nitrile rubber) for dusty/humid environments or non-contact labyrinth seals for high-speed applications up to 3000rpm.

Key Parameters

Parameter	Value
Inner Diameter (d)	90mm
Outer Diameter (D)	190mm
Width (B)	64mm

Performance Advantages

Exceptional Load Capacity: Basic dynamic load rating of 450kN and static load rating of 610kN
Superior Self-Aligning: Automatically compensates for shaft deflection, extending service life by over 30%
Robust Wear Resistance: HRC60-65 hardness with phosphated surface, operational from -40°C to 120°C
Low Friction: Coefficient as low as 0.0015 with vibration velocity below 65dB

Material Quality

Rings and rollers use high-purity bearing steel (GCr15SiMn) processed with vacuum degassing for exceptional density. Brass cage (H62) provides excellent thermal conductivity and mechanical strength for reliable performance under heavy loads.

Application Fields

Heavy Industrial Machinery: Mining crushers, metallurgical rolling mills
Construction Machinery: Gearboxes in loaders/excavators, crane winches
Energy Equipment: Wind turbine main shafts, hydropower water turbines
Papermaking & Textile: Calender rolls, drying roll groups, dyeing equipment

Installation and Maintenance

Use specialized tools for installation with recommended working clearance of 0.12-0.25mm. Lubrication options include extreme pressure lithium-based grease (NLGI Grade 2) or ISO VG 46/68 oil for high-speed applications. Monitor bearing temperature (below 70°C) and check for abnormal vibration/noise during regular maintenance.

The 22318CA bearing represents engineering excellence with high-strength construction, exceptional self-aligning capabilities, and broad adaptability to diverse operating conditions, making it indispensable for modern industrial machinery.
