 LBBR linear ball bearings 
The recently developed compact LBBR linear ball bearing is of a patented design.  The bearing comprises  a plastic cage  carrying hardened steel raceway segments and guiding the ball sets. The bearing conforms to dimension series 1 of ISO 10285. The LBBR raceway segments have been designed to maximise the length of the load carrying zone. A high load bearing capacity is therefore possible with a resulting long service life. The design of the plastic cage is entirely new and has been optimised. The key feature is that all the balls in the bearing run on the same pitch circle diameter which allows ball recirculation to take place smoothly with no resulting cage loads. Ball diameter can be maximised with this design  of cage with implications not  only for load capacity and life but also on  running quality. T he seal design on this  new bearing type has also been improved.  The sealed variant is fitted with integral double lip seals. These seals have an inner lip that prevents escape of  lubricant from within  the bearing and an external lip to wipe the shaft surface as the bearing moves. The unsealed bearing is fitted with noncontacting  shields that protect against major  contamination from the bearing. The  linear ball  bearings  LBBR, need not be  secured axially in the  housing  provided the housing bore is correct.
Stainless 
The application of linear bearings has been extended by this new type with the introduction of a corrosion resistant variant 
Raceway segmentsand balls can be specified  in high alloy  stainless steel by adding the suffix HV6 to the  designation, e.g. 
LBBR 16-2LS/HV6.  In combination  with our stainless steel shafts, the linear ball bearing LBBR thus offers the possibility of 
realising a design completely of stainless steel.

LBCR .. A linear ball bearings

LBCR .. A l inear ball  bearings comprise a cage  in which the balls are guided, together with the raceway segments and the seals or shields.  By virtue of  their exceptionally  long track length and the  machined raceway osculation they are able to accommodate heavy loads. LBCR .. A linear ball bearings, with their optimised raceway segments and position for maximum load carrying capacity, can be mounted in closed as well as adjustable housings. When these  bearings are mounted i n a closed housing, the  tolerance of  the inscribed diameter of the ball set and hence the operating  clearance is determined by the tolerance of the housing bore. When mounted in slotted housings the linear guides can be adjusted to the particular application, to provide either operating clearance or preload. LBCR .. A linear ball bearings must be located in axial direction.
