SHS 45 LC SS THK linear guide block

Main description

The SHS 45 LC SS THK linear guide block is a high precision linear motion component designed for applications requiring smooth movement, high rigidity and reliable performance under heavy loads.

A linear guide block is a recirculating ball carriage that moves along a linear rail, providing controlled motion with minimal friction and high accuracy. The SHS 45 LC SS belongs to the advanced THK SHS series, which uses a four row ball circulation system to ensure equal load distribution in all directions.

The LC version features an extended block length, increasing load capacity and improving stability, especially in applications exposed to moment loads and dynamic forces. The SS designation indicates stainless steel construction, making this model suitable for environments requiring corrosion resistance and high cleanliness.

Construction and design

The THK SHS 45 LC SS linear guide block is built with a four row recirculating ball system that enables high load capacity in radial, lateral and moment directions.

The extended LC design provides a larger contact area between the block and the rail, improving rigidity and reducing deflection under load. The stainless steel SS version enhances resistance to corrosion, moisture and chemical exposure.

Precision manufacturing ensures smooth ball circulation, low friction and consistent performance even at high speeds and repetitive cycles.

Industrial applications

This linear guide block is widely used in systems where precision linear motion and durability are critical.

Typical applications include:
CNC machines and machining centers
industrial automation and robotics
production lines and assembly systems
medical and laboratory equipment
