Product Description

Chrome Steel Insert Bearings NA300 Series are located on the shaft by means of an eccentric locking collar, grub screws in the inner ring, an adapter sleeve, drive slot or fit. Radial Insert Ball Bearings are particularly easy to fit, suitable for drawn shafts of grade h6 to h9 and, with a few exceptions, can be relubricated.Steel Insert Bearings NA300 Series share high precision and high quality manufacturing processes.

Steel Insert Bearings NA300 Series

HIGH TEMPERATURE GREASES
For quieter, smoother, more efficient running bearings under higher radial loads and a true center line, there`s only one choice, ACCU-LOC.
CONCENTRIC LOCKING
The uniform grip of the inner race to the shaft results in lower noise and vibration levels at high speeds.
SHAFT PROTECTION
The concentric locking force significantly reduces the chance of marring or damaging the shaft.
