Linear guides manufacturers
Linear guides are manufactured by specialized motion-component producers that make rails, carriages/blocks, and matched bearing elements; buyers should look for manufacturers that provide compatible rail-and-block systems, clear load and accuracy data, and application-specific products (ball vs roller, recirculating vs profile). Typical manufacturers range from global bearing/OEM firms to companies focused on linear-motion systems.

What to specify in your RFQ
Manufacturers quote faster and more accurately when your request covers these points.
- Rail and carriage/profile type
Specify whether you need ball-based linear guides, roller guides, profile rails, or dry (polymer) guides so suppliers match component geometry and recirculation type.
- Dimensions and mounting
Provide rail length, carriage length/width, mounting hole patterns and spacing, and any required tolerances or fits.
- Load and dynamic requirements
State maximum static and dynamic loads, moments, expected life (L10 or equivalent), and peak shock/impact loads.
- Accuracy and stiffness class
Give required positional accuracy, repeatability, straightness, and rigidity or deflection limits for the application.
- Operating environment
Describe temperature range, contamination (dust, chips), washdown/cleanroom needs, and lubrication preferences (greased, lubrication-free).
- Quantity and delivery
Specify unit quantities, required delivery schedule or lead time, and expected annual volumes for quoting MOQ or production planning.
- Surface finish and materials
Indicate rail/carriage material, surface hardening/coating (e.g., induction hardened, stainless, corrosion-resistant coatings) if relevant.
