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.
