23200 Series Spherical Roller Bearing

The 23200 series spherical roller bearing accommodates radial loads and bidirectional axial loads through its double-row symmetrical roller configuration. The outer ring incorporates a spherical raceway that enables self-alignment, compensating for angular misalignment between shaft and housing. This series features an optimized roller geometry with a machined brass or steel cage that maintains roller spacing under varying load conditions. The bearing operates within a temperature range of -30°C to +150°C for standard steel retainers. Each unit includes a logarithmic profile on rollers and raceways to reduce edge stresses. The internal clearance group CN is standard, with C3 and C4 available upon specification. Load ratings follow ISO 281 calculation methods.

Frequently Asked Questions

What lubrication method applies to the 23200 series?

Grease lubrication with NLGI grade 2 or 3 lithium-complex soap is standard for speeds below 70% of limiting speed. Oil circulation or oil bath lubrication applies when operating temperatures exceed 100°C or speeds approach the limiting value.

How to select the correct internal clearance?

CN clearance suits normal operating temperatures between 20°C and 80°C with steel shafts. C3 clearance applies when temperature differential between inner ring and housing exceeds 15°C or when interference fit exceeds 0.05% of shaft diameter.

What indicates bearing replacement necessity?

Increase in operating vibration amplitude exceeding ISO 10816-3 thresholds, rise in bearing housing temperature above 95°C under consistent load, or audible metallic grinding during rotation.

Installation Precautions

Mounting method

Use induction heater to expand inner ring uniformly. Maximum heating temperature limited to 110°C for standard bearing steel. Do not exceed 120°C to avoid tempering effects on hardness.

Shaft fit recommendation

For rotating shaft applications, use interference fit with f6 or m6 tolerance. For stationary shaft applications, use h6 or h7 transition fit. Housing bore tolerance recommended as H7 for split housings or P6 for solid housings.

Lubrication interval

Regrease every 1000 operating hours or three-month period under normal conditions. For ambient temperatures above 70°C, reduce regreasing interval to 500 hours.

Storage conditions

Store in original packaging with corrosion inhibitor intact. Ambient humidity below 65% RH, temperature range 0°C to 40°C. Avoid stacking more than three pallets.
