Shaft carriers / shaft blocks
Among shaft carriers, a distinction is made between shaft blocks and shaft supports. Shaft blocks support the shaft only at its ends; shaft supports typically run the entire length of the shaft and therefore require the use of open linear bearing units. LSCS shaft blocks are made of cast aluminium and designed to grip the end of the shaft. These blocks are supplied as standard with two holes drilled in the base for attachment. LSCS shaft blocks are suitable for shaft diameters ranging from 8 to 80 mm. LSNS and LSHS shaft blocks are made of extruded aluminium. They can be attached by through bolts or they can be bolted, via threaded holes, directly to the support surface.
LSNS and LSHS shaft blocks are available for shaft diameters ranging from 12 to 50 mm. LEBS/LEAS tandem shaft blocks To match the duo and quadro linear bearing units with ISO series 1 linear ball bearings (LBBR), LEBS tandem shaft blocks are available in the “A” design, where the shaft block is fixed and the linear bearing moves axially. LEBS shaft blocks are available for shaft diameters ranging from 12 to 50 mm. For units with ISO series 3 linear ball bearings (LBC/LBHT) LEAS tandem shaft blocks are available in both the “A” and “B” design. The “B” design enables axial movement of the shafts through a fixed linear bearing unit. LEAS shaft blocks are available for shaft diameters ranging from 8 to 50 mm.
LRCB/LRCC shaft supports For heavily loaded linear bearing units and/or long track lengths, SKF recommends the use of shaft supports to eliminate shaft bending. For these applications, continuous or at least partial support of the shaft is necessary. SKF offers shaft supports for shaft diameters ranging from 12 to 80 mm. There are two types of shaft support: the LRCB with predrilled holes and the LRCC without holes. Note: Shaft supports require the use of open design linear bearing units.
