SBL-D Series

Notes

For spindles with exceptionally restricted or narrow space, this model is ideal in that it is super thin and requires no additional tooling or components to do its job. For thread sizes under M45 we offer the SBL-D with 3 lock screws, and for larger threads we offer the SBL-D with 6 lock screws. Balance adjustment screw holes can be fitted with screw-in plugs(option), eliminating high frequency noise and subsequent vibration.
