Linear guide type R

Linear bearings based on linear guides type R can be filled by flat bearing cages with balls (type AK) or flat bearing cages with crossed bearing rollers (type AA or AC). Cross roller slides type R can work with linear guides type RD and with recirculating units Type SK, SKD, SR, and SKC.

Cross roller slides type R normally manufactured from tool steel 1.2842. The hardness is between 58 and 62 HRC, or min. 54 HRC for certain corrosionresistant models (material No. 1.4125)

Cross roller slides type R are fully compatible and can replace LWR, VR, SV, RSD, GR slides.

Options:

SQ - special quality, high requirements

SSQ - super special quality, most stringent requirements

RF - corrosion resistant

EG - inlets rounded

EE - for cages EE

ZG - linear guides ground together (pic.1.)

HA - of height matched linear guides in pairs (pic.2.)

DU - coating type Duralloy^®

Pic.1. ZG - Multi-section linear bearings. If the required total length of the guide is greater than the maximum length indicated in the catalogue, the individual guideways will be ground together. The offset between the individual guide rails should not exceed 0.002 mm. The linear tolerance L should lie between +/- 2 mm. When assembling the guideways, the numbering at the junction must be observed

Pic.2. HA - Tolerance of height matched linear bearings. With gravity loaded guides which are matched for height, a tolerance of ±0.01 on dimension A +0/-0.3 from A1 to A2 is held and the parts are marked accordingly. If several sets are supplied they are numbered consecutively.
