Linear Guide Rail And Block

Product Introduction

The RGW45CC roller guide block is a flange-type carriage engineered as a direct HIWIN compatible replacement for the RG45 roller guide rail system. Driven by precision rollers instead of balls, it is a heavy duty linear guide block that delivers higher rigidity and load capacity than ball-type guides of the same 45 mm size, while keeping travel smooth and accurate. If your equipment needs a spare carriage for RG45 rails, this RGW45CC roller guide block is a drop-in HIWIN compatible linear guide block.
Why choose this 45mm flange linear guide block? Compatibility first: every RGW45CC roller guide block we ship is dimensionally interchangeable with the original model and runs directly on standard RG45 rails, so a retrofit needs no extra machining. Performance second: the roller structure gives this heavy duty linear guide block high rigidity, high load capacity and low friction, which suits continuous production. Maintenance third: end seals and grease fittings are pre-installed, so the HIWIN compatible linear guide block runs for long intervals between services.

Core Product Features

Ultra Compact & Lightweight Design

Narrow 7mm rail profile, ultra-small cross-section structure, greatly saving internal installation space of mini machines; low self-weight reduces equipment moving load, ideal for portable and mini precision devices.

4-Point Gothic Arch Contact, Equal Load in 4 Directions

Adopts 45° gothic arc raceway & 4-row recirculating ball structure, evenly bears radial, reverse radial, horizontal and overturning torque loads. Higher rigidity than 2-row miniature guides, stable motion under complex offset loads without jitter.

Built-In Ball Retainer, Interchangeable Structure

Integrated micro steel ball retainer prevents balls falling off when disassembling the block from rail, convenient for installation, maintenance and replacement. Same precision grade rails & blocks can be freely matched, no need to pair as original sets, greatly reduce spare parts inventory cost.

Ultra-Low Friction, Smooth & Low Noise Movement

Superfinishing grinding on rail raceway surface, friction coefficient ≤0.003; rolling friction instead of sliding friction, low driving force, high-speed stable operation, running noise ≤45dB, suitable for silent precision testing equipment.

Have Some Questions
About Our Linear guideways.

What is the difference between ball and roller linear sliders, how to choose?

Ball sliders suit light load, high speed & low noise applications like automation and 3D printers. Roller sliders feature high rigidity, heavy load capacity and impact resistance for CNC machines and woodworking equipment.

How to select preload grade Z0/Z1/Z3 for sliders?

Z0 zero preload: low resistance for simple conveyors; Z1 light preload eliminates clearance for CNC & packaging machines; Z3 heavy preload for ultra-precision 5-axis machines and inspection equipment.

What causes abnormal noise of linear guides & sliders? How to fix it?

Insufficient lubrication, dust contamination, unparallel mounting base or damaged steel balls. Install self-lubrication and double dust-proof accessories, re-calibrate mounting surface or replace defective sliders.

Which sliders fit dusty woodworking & humid food machinery?

Sliders with double dust seals and scrapers, stainless steel rails or anti-rust coating are recommended. E2 self-lubrication units prevent chips and powder entering circulation circuits.

Can linear guide rails be customized to non-standard lengths? What’s the maximum single length?

Custom cut-to-length available. Max single rail length is 6m; longer stroke adopts spliced rails with professional joint processing.

Installation difference between flange, high-profile and low-profile sliders?

Flange sliders with through holes have low mounting height and balanced load; high-profile sliders offer higher load capacity; low-profile sliders fit narrow internal equipment space.

Application for C/H/P/SP/UP accuracy grade linear guides?

C/H: packaging & general woodworking machines; P: CNC milling & standard automation; SP/UP: 5-axis machine tools, precision testers and SLA 3D

Slider jerks and moves unsmoothly, how to troubleshoot?

Check flatness of mounting base, evenly tighten bolts, clean foreign particles inside circulation paths, replenish grease and correct rail parallelism.

Can you supply integrated linear modules with matching ball screws, guides and sliders?

Yes. We provide one-stop customized linear motion modules, matched with proper ball screws and guides according to load, stroke and accuracy requirements, delivered as finished slides ready for assembly.

What is the lead time for samples and mass orders?

Standard samples: 1–3 days; non-standard modified sliders with special protection: 3–7 days; mass production orders: 7–15 days, flexible scheduling for bulk orders.
