Application and Benefits

The Linear Optical Axis has broad applications in automatic transmission devices such as engraving machinery, woodworking machinery, printing machinery, and industrial robots.

A significant advantage when installing the cylindrical linear guide is the use of non-ball type polymer liners on the shaft. High-performance bearing-grade materials suitable for aluminum or other substrates can be used to provide good load capacity (20% of the ball liner’s load capacity) and a lower friction coefficient ranging from 0.05 to 0.25.

These liner bearings can smoothly operate in harsh environments with particles that could damage the tightly sealed ball liners. They can also function normally under impact load damage in the ball bearing system. Noise from ball circulation may be a problem in ball liners or square guide rail bearings, but this issue is almost non-existent for the aforementioned liner bearings.

With a larger contact area, there is no need for hardened steel shafts with ball liners. Stainless steel shaft systems can be used, which are suitable for clean environments like the semiconductor and pharmaceutical industries, as well as harsh environments like the food processing industry.

The SBR16’s unique features and advantages make it an ideal solution for high-precision machinery structures. The moving and fixed elements of the linear guide do not use an intermediate medium, but rolling steel balls, suitable for high-speed movement, low friction coefficient, and high sensitivity. These attributes meet the working requirements of moving parts, such as machine tool carriages and slide boards. However, if the force acting on the steel ball is too large, and the steel ball undergoes a pre-loaded duration, it may lead to increased movement resistance of the bracket.

ZLV’s Open Linear Optical Axis Guide Slider Bearing SBR16 brings precision, efficiency, and durability, tailored to the customers’ needs.
