Spring Slider 5in Dual Bearing 21in Fine Thread

The Spring Slider 5in Dual Bearing 21in Fine Thread is a precision linear bearing assembly designed for high-load automotive and machinery applications where smooth, repeatable motion is essential. This product is ideal for technicians and fabricators who require reliability in mission-critical setups, such as custom suspension components and adjustable performance systems.

Constructed with precision-ground steel races and hardened ball bearings, the Spring Slider operates on a 21-inch fine-thread rod that allows for micro-adjustments and repeatable positioning. The dual-bearing configuration enhances lateral stability and load distribution, while the 5-inch stroke enables significant travel distance for multi-stage adjustment mechanisms. Fine-thread geometry minimizes the risk of vibration-induced loosening, ensuring precise incremental changes.

This assembly is particularly beneficial for those involved in suspension tuning and custom fabrication, providing the durability and low-friction travel necessary for high-performance applications. Whether you're building a competition-grade engine hoist or designing adjustable platforms, the Spring Slider is engineered to meet the demands of professional-grade work.
