FL / FLL / FLS

High Rigidity and High Performance

Circular-Arc Groove, 4-way raceway, 2-point structure absorbs the instrumental errors and creates self-aligning smooth movement, even under high load operation.

Equal Load Carrying Capacity in all Directions

The circular-arc structure with 2-point contact at a 45 degree angle creates the same load in all directions, which enables the block to bear equal load in radial, reversed radial and lateral directions. This translates to a versatile installation in any direction.

Design Flexibility

Multiple block styles are completely interchangeable on rail of same size, without compromising system accuracy. Several block and rail options are stocked such as dust-free seals, Raydent Coating for rust prevention and bottom-mount rail.
