Steel Needle Cage Bearing Without Inner Ring 28*39*30 RNA69/22
Description,
Textile bearings is textile machinery bearings, because of the bad
working environment, so the textile machinery require long service
life and high load .generally require it has long life span, heavy
load, high speed, low noise, smooth operation performance.
Warp knitting machine are commonly used models have NK45/30 (45 X
55 X30), NK20/16, NK 20/20 , NK40 / 30, such as K30 37 18 needle
roller bearing, and F - 602380 (20 X36 X20.4), the F - 589414 (21
X30 X25), F - 213114.1 and other non-standard cylindrical roller
bearing, has a strong bearing capacity, stable operation, long
service life, high precision, etc.
Very suitable for warp knitting machine and other textile machinery
on bearing requirements.
