TOSHIBA Welker Bearing Linear Guides and Wedge Components

Welker Bearing Linear Guides and Wedge Components

Product basic positioning and core application areas

1. Product category and positioning

The linear guide and wedge components of Welker Bearing are both high-precision linear motion parts, with the core positioning being:

Linear Slides: Achieve smooth and precise linear reciprocating motion of equipment components, undertaking dual functions of guidance and load-bearing;

Gib Assemblies: Used in conjunction with linear guides to adjust guide clearance, compensate for wear, improve motion accuracy and stability, and some models can be used independently as guide components.

2. Core application scenarios

Both types of products focus on the demand for "high-precision linear motion" in the industrial field, and typical application equipment includes:

Machine tools: worktable guidance for lathes, milling machines, grinders, and machining centers;

Automation equipment: robot guide rails, automated production line conveyor mechanisms, precision positioning platforms;

Heavy industrial equipment: linear moving parts of metallurgical machinery, heavy-duty presses, and mining equipment;

Special equipment: precision guide rails for aerospace component processing equipment and medical imaging equipment (such as CT and MRI).

Product details of Linear Slides

1. Product series classification

According to the structure, load-bearing capacity, and accuracy level, linear guides are divided into multiple standard series. The core series and characteristics are as follows:

Series name, structural characteristics, core advantages, applicable scenarios

Standard Linear Slides single/double track structure, using steel guide rails and sliders, with built-in lubrication grooves for strong versatility, moderate cost, easy installation, universal machine tools, and lightweight automation equipment

Heavy Duty Linear Slides: Thickened guide rail walls, reinforced slider materials (high carbon steel/alloy steel), multiple sets of rolling elements (or sliding friction pairs) with strong load-bearing capacity (static load can reach several tons), good impact resistance. Heavy duty machine tools, metallurgical machinery, and press machines

Precision Linear Slides (Precision Series) guide rail surface precision grinding (roughness Ra ≤ 0.8 μ m), adjustable clearance, equipped with position feedback interface (optional), high motion accuracy (positioning error ≤ 0.01mm/m), good repeatability Precision machining equipment, medical equipment, aerospace parts processing

Custom Linear Slides can adjust the length of guide rails, number of sliders, installation hole positions, and material (such as stainless steel) according to customer needs to adapt to special installation spaces and working conditions. Non standard equipment and customized scenarios for special industries can also be used

Gib Assemblies Product Details

1. Product type and structure

Wedge components, as the "precision compensation and clearance control components" of linear guides, are mainly divided into two categories:

Type Name Structure Composition Core Functions

Solid Gibbs integrated wedge block (inclined angle 3 ° -10 °), fixing bolt, and locating pin are used to fix the guide rail clearance, suitable for scenarios with low wear and stable working conditions

Adjustable Gibs: Split wedge block (active wedge+passive wedge), adjusting bolt (top screw/pull rod), locking nut can adjust the gap in real time (compensating for wear or assembly errors), suitable for high-precision or high wear working conditions
