Profile rail guides improve precision
and life
An innovative linear motion guide range from SKF has been developed to minimise friction and maintenance costs significantly, while maintaining repeatability and precision under heavy loads
An innovative linear motion guide range from SKF, the leading knowledge engineering company, has been developed to minimise friction and maintenance costs significantly, while maintaining repeatability and precision under heavy loads The simple LLR series provides high torsional stiffness and strokes, up to a maximum of 6m for applications where precision and smooth motion is vital, such as in automated factory devices, laboratory equipment, and in the materials handling industry

SKF's fan upgrade solutions offers a 'systems approach' to fan maintenance and reliability that will help industrial facilities increase fan performance while decreasing maintenance and downtime.
SKF Y-bearing units designed to take the heat
The latest generation of Y-bearing units for extreme temperatures from SKF are optimising productivity and minimising costs in a diverse variety of industrial applications
By comparison with competing products, the LLR linear guide carriages can incorporate composite inserts, which act as lubrication reservoirs, extending component service life and eliminating the need for frequent lubrication and costly maintenance.
The carriages also feature optimised ball recirculation geometry and special plastic ball separators, which reduce friction and vibration still further, providing an almost silent, high speed operation.
The new LLR linear motion guides are able to withstand far heavier loads than traditional guides, while maintaining high levels of precision and repeatability at all times.
This is achieved by the profile configuration between carriage and rail, which provides structural rigidity and motion stability.
Torsional stiffness prevents rail misalignment and enhances the contact points with ball bearings for greater smoothness of movement and a long low maintenance service life.
The modular LLR profile rail guides offer a high degree of flexibility and efficiency, with carriages providing a static bearing capacity of between 7.8 and 128.5 kN and a dynamic capacity from 6.8 to 90kN.
Eight various types of carriage are available in five different sizes, with rail widths ranging from 15 to 45mm and system heights from between 24 and 70mm.
Standardised rails are available with or without cover seals and enable interchangeability for all carriage versions.
Ready to install, the latest LLR linear motion guides can be customised to meet the most demanding application requirements, with complementary product consumables, such as external scraper seals, being readily available. Request a free brochure from SKF UK ...
