RGH25CA Roller Type Linear Guide Block for CNC Machines

TranzBrillix Linear Motion is a China-based manufacturer and supplier of linear motion components, focusing on linear guideways, ball screws, linear bearings, and related transmission parts for automation equipment, CNC machinery, packaging systems, 3D printers, and industrial motion assemblies.

Our product range covers both in-house manufactured components and original-brand linear motion products. This allows customers to source cost-effective replacement parts, customized assemblies, and recognized international brands from one supplier.

TranzBrillix supplies HIWIN-type linear guideways with commonly used mounting dimensions for replacement, machine building, and equipment maintenance projects.

Main series include:

HG Series — Heavy Load Ball Type Linear Guides
Available in square and flange block types, with rail widths from 15 mm to 65 mm. Suitable for CNC machines, automation lines, cutting equipment, and general industrial motion systems.

RG Series — Roller Type Linear Guides
Designed with roller rolling elements for higher rigidity and load capacity compared with standard ball-type guides. Commonly used in heavy-duty CNC equipment, precision machining centers, and applications requiring stronger resistance to moment loads.

EG Series — Low Profile Linear Guides
A compact linear guide series for machines with limited installation height. Available in square and flange block structures, with common rail widths from 15 mm to 35 mm.

MG Series — Miniature Linear Guides
Available in stainless steel and carbon steel options, with compact rail widths from 5 mm to 15 mm. Suitable for small automation devices, measuring equipment, compact slides, and 3D printer motion systems.

For standard guideway production, rails are commonly made from S55C steel, while blocks are made from SNCM220 alloy steel. Accuracy grade, preload, rail length, and block type can be selected according to the application.

TranzBrillix supplies rolled and ground ball screws for positioning and transmission systems.

Available options include:

• Rolled C7 ball screws for standard automation and economical transmission applications
• Ground C5 and C3 ball screws for applications requiring higher positioning accuracy
• Customized ball screw machining, including special shaft lengths, end machining, nut matching, and non-standard designs

We support customers with drawing review, model confirmation, end-machining requirements, and replacement selection when the original part number is incomplete or obsolete.

Our linear bearing range includes standard metric and inch-size linear bearings, open type, long type, flange type, and housing-mounted options. These products are often used for equipment repair, guide shaft systems, packaging machines, textile machinery, and light automation structures.

We can also supply related components such as linear shafts, stainless steel shafts, shaft supports, ball screw supports, couplings, ball nut housings, and ball splines.

In addition to TranzBrillix products, we help customers source original-brand linear motion components from manufacturers such as TBI, ABBA, Rexroth, and other recognized brands.

This is useful for customers who need brand-specific replacement parts, urgent stock checking, cross-reference support, or mixed purchasing of standard and branded components.

TranzBrillix works with CNC machining, precision grinding, assembly, inspection, and packaging processes to support both standard and customized linear motion orders.

Our team focuses on:

• model selection and replacement checking
• dimensional confirmation before production
• preload and accuracy selection for linear guides
• ball screw end machining and nut matching
• inspection before shipment
• export packaging for rails, screws, and precision components

For non-standard parts, customers can provide drawings, samples, photos, or existing part numbers for technical review.

Customers choose TranzBrillix because we combine manufacturing capability, engineering support, and flexible sourcing for linear motion components.

We support:

• standard linear guideway supply from miniature to heavy-duty sizes
• HIWIN-type replacement selection for HG, EG, RG, and MG series
• rolled and ground ball screw solutions from C7 to C3 accuracy grades
• original-brand sourcing for selected international brands
• customized machining and application-based selection
• responsive support for distributors, machine builders, and maintenance teams

TranzBrillix Linear Motion is built for customers who need practical linear motion solutions, not only catalog numbers. Whether the project requires standard stock, a replacement model, or a customized ball screw assembly, we help confirm the technical details before supply.
