Standard Bearings<br />
which are fixed, Eccentric type (E), adjustable and Double Eccentric type (DE)* 5 which have sufficient adjustment to<br />
enable a carriage to be disengaged from the Slide (see application drawing on page 8).<br />
All Through Hole Fixing types are available in a Controlled Height version (CH)* 7 which minimises variation between<br />
Bearings in respect of the important 'B1' dimension. This may be desirable in some high precision applications.<br />
The Blind Hole Fixing type (BH) allows mounting into a solid machine base where through mounting holes are not<br />
possible, or where the thickness of the mounting plate is too great (see application drawings on page 16). The Blind Hole<br />
Fixing type is also useful where adjustment from the front is preferred or where access to the opposite side of the mounting<br />
hole is restricted. They are available in Concentric type (C) which are fixed, or Eccentric type (E) * 6 which are<br />
adjustable.<br />
All Bearings are greased for life internally. Customers are strongly recommended to provide lubrication to the interface<br />
between Bearings and Slide by specifying Hepco Cap Seals which fit over the bearings, or by using Hepco Lubricators.<br />
Lubrication greatly increases load capacity and life.<br />
