Open Sided Aluminium Housings for Open Type Ball Bushings
If the direction of the load is acting towards the open side of an Open Type Ball Bushing the load capacity is severely reduced.
These Open Sided Linear Sets have been developed to overcome this disadvantage and to permit selective circumferential positioning as well as high rigidity of the open type ball bushing assembly.
The housings are equipped with Standard Ball Bushings with two seals that provide high precision and a minimum radial clearance. The bushings are secured in the housing by means of grease nipple screws.
When exceeding operating temperatures of 80ºC unsealed ball bushings NB30 manufactured entirely from steel are available.
Ordering reference number LE71-0.. (shaft diameter) instead of LE71-2..
If corrosion resistance is required these units can be supplied with KB53 ball bushings.
Ordering reference number LE71-5.. (shaft diameter)
NB. Loads are assumed to be acting vertically.
