Linear Ball Bearing HL

 

Application


The type HL has been developed to propose a linear bearing adapted to high loads and high radial torques. This makes it very appropriate for vertical applications. The three (external) grooves make the mounting to be easy and the high permissible temperatures make it perfectly suitable for injection moulds.


Design


100 Cr6 steel housing, hardened to 63 HRc, ground (lapped for quality grade A).
Ball tray in brass.
Precision 100 Cr6 steel balls.


Scopes


Vertical presses, peripheral machine devices, moulds industry, assembly industry, etc...


Precision Grades


BA = Medium Improved
A = Good
XA and ZA on request

Allowed Temperatures


-30° à + 200°C (without seals)
