[ ! ]Blocks and rails are not sold as separate items. Normal Clearance Type has guaranteed radial clearances and accuracies as sets of blocks and rails.
■Precautions for Use
[ ! ]Blocks are equipped with retainers (wire) to prevent balls from derailing. For blocks, see >> Click here
[ ! ]Radial clearances and accuracies are not guaranteed if the blocks and rails are interchanged from the original set combinations.
[ ! ]Straight grooves are provided on datum planes. Be sure to match the datum lines when using.
[ ! ]Rails cannot be connected end to end.
[ ! ]Running parallelism is the value measured after the rail is mounted (it is not the value measured before the rails are fastened with screws.).
■Others
· Filled with Lithium soap based grease (Alvania Grease S2 by Showa Shell Sekiyu K.K).
· Grease Fittings: Straight Type for H24 and Angled Type for H28 and H33.
· Grease Fitting is screw-in type, and thus, can be repositioned.
