51164 400 mm 320 mm 164 mm Frequently Asked Questions about 51164 Thrust Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
To safeguard CHG Bearing 51164 against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (320 mm x 400 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
Absolutely. The CHG Bearing 51164 Thrust Ball Bearings is a 1:1 direct interchange for renowned brands, matching part numbers: SKF 51164, FAG 51164, NSK 51164. It shares identical envelope boundary dimensions, load capacities, and shaft fits, allowing instant drop-in replacement without retrofitting your machinery.
As a primary manufacturer, CHG Bearing supports both trial batch evaluations and container-load supply for 51164. Standard catalog sizes are stocked for rapid 3–7 day dispatch, while high-volume OEM production runs typically dispatch within 30–45 days.
To extend the trouble-free lifespan of CHG Bearing 51164, preventive maintenance routines should monitor operating housing temperature (normally maintaining below 70°C) and conduct regular vibration FFT analysis to identify early raceway micro-pitting before unexpected line halts occur.
