Quadro linear tables, non-driven
The closed LZBU quadro linear table consists of a closed quadro linear bearing unit, two tandem shaft blocks and two shafts of the required length. The bearing unit is fitted with four LBCD-LS self-aligning linear ball bearings, each sealed at one end. The LZBU-“A” design enables axial movement of the linear bearing unit, i.e. the shafts are fixed to the machine bed via LEAS-“A” shaft blocks. The LZBU-“B” design is provided with LEAS-“B” shaft blocks. This combination enables the shafts to travel with the shaft blocks in applications where the linear bearing unit is fixed. LZBU quadro linear tables can be supplied in sizes ranging from 8 to 50 mm. Size 8 tables are not self-ali-
gning and are not designed for relubrication. The description of the closed quadro-linear table also applies to the combination of series 1 LQBR … 2LS quadro linear bearing units with twin LEBS tandem shaft blocks and shafts (on special request only). Shaft diameters range from 12 to 50 mm. The open LZAU quadro linear table comprises the open quadro-linear unit and two high precision shafts with shaft supports. The bearing unit is fitted with four LBCF-“A-LS” selfaligning linear ball bearings, each sealed on one end. The length of these tables is dictated by the distance between centres of the attachment

holes in the LRCB shaft supports. The total length should always be a multiple of this distance. LZAU are available in sizes ranging from 12 to 50 mm.
