The SKF SMSW LPAST self-aligning support is designed to hold and align linear guide shafts in precision motion systems. It accommodates minor misalignment during assembly or from structural deflection, making it suitable for machine tools, automated equipment, and conveying systems. MR supplies this SKF series and can assist in matching the support to your shaft size and mounting configuration.

The part number breaks down as follows: SMSW indicates the SKF self-aligning support category for linear guide shafts. The following number is the nominal shaft diameter—options include SMSW 16LPAST, SMSW 20LPAST, and SMSW 24LPAST. The LPAST suffix denotes the specific design variant, including mounting geometry and surface treatment. When ordering, use the complete code as shown on your equipment or drawing.

These supports are common in applications where linear guidance must remain consistent: machine tools, machining centers, automation, manipulators, precision conveyors, and test benches. They are also used in food and pharmaceutical environments where clean operation and repeatable motion are priorities. The support works with the shaft and linear bearing or bushing to keep the assembly aligned throughout the stroke.

When selecting a support, begin with the shaft diameter and the mounting style. Even though the design is self-aligning, careful installation extends system life. Check alignment between supports, ensure shaft seals are intact, and keep the system lubricated—contamination from chips or dust accelerates wear. Tighten mounting screws evenly and confirm smooth shaft movement before final torque.

For replacements, SKF SMSW supports may interchange with other brands that meet the same linear shaft standard, but diameter alone is not enough. Compare mounting height, hole spacing, and mounting type. Send the dimensions of your current support or a photo, and MR will cross-reference it with the SKF line.
