SK series linear shaft supports are compact shaft support units designed for secure mounting and stable positioning of linear shafts in industrial equipment and automation systems.
Built with a durable aluminum housing and clamping structure, our SK supports provide reliable shaft holding, easy installation and stable performance in linear motion applications.
We manufacture SK linear shaft supports in a wide range of bore sizes and dimensions. For replacement orders, confirm the SK support bore, base width, shaft center height, mounting-hole positions and clamping screw arrangement against the existing machine drawing. SK supports hold the linear shaft in position; the moving carriage requires a separate compatible bearing unit. Standard sizes, drawing-based OEM requirements and bulk orders are available directly from our factory.













Dimensions are in mm. Mass is in g. The source catalog labels these models as SH(SK).
