Self-Aligning and Maintenance Friendly

SKF LUCR linear bearing units are engineered with self-aligning capability, catering to minor misalignments in mounting surfaces. The design supports easy maintenance with pre-lubrication and options for relubrication, optimizing service intervals and reducing downtime.

Corrosion Resistant for Varied Environments

Equipped with thermoplastic or aluminium housings and bearing steel inner components, the LUCR units resist corrosion effectively, making them a preferred choice for environments where reliability and durability are crucialsuch as automation lines and precision machinery.

Versatile Mounting and Application Flexibility

Available as flanged or pillow block mounting types, LUCR units fit a range of industrial and automation setups. Their single-row structure and robust build accommodate dynamic loads up to 1400 N, maintaining precision under demanding operational speeds and variable temperatures.

FAQs of SKF Linear bearing units LUCR:

Q: How does the self-aligning feature of SKF LUCR linear bearing units benefit my installation?

A: The self-aligning capability allows the bearing unit to compensate for minor misalignments during installation, ensuring smooth motion and reducing the risk of excessive wear, especially in demanding automation or industrial machinery applications.

Q: What maintenance processes are needed for the LUCR linear bearing unit?

A: SKF LUCR units come pre-lubricated for immediate use, but they also allow for relubrication if extended performance is required. Contact seals on both sides help retain lubrication and minimize contamination, making ongoing maintenance straightforward and efficiency-driven.

Q: When should I choose a thermoplastic housing versus aluminium for LUCR units?

A: Thermoplastic housings are suitable for applications where reduced weight or higher resistance to specific chemicals is needed. Aluminium housings offer enhanced mechanical strength for more robust industrial setups. Your choice should be aligned with the applications environmental and load conditions.

Q: Where can LUCR bearing units be used, and what applications are they best suited for?

A: LUCR units are ideal for automation setups, precision equipment, and various types of industrial machinery that require smooth, reliable linear movement. Their corrosion-resistant construction makes them suitable for a variety of operational environments.

Q: What is the limiting speed and load capacity of the SKF LUCR unit with a 25 mm bore?

A: With a 25 mm bore, the SKF LUCR bearing unit supports dynamic loads of up to 1400 N, static loads of 1120 N, and has a limiting speed of up to 5000 rpm, meeting the needs of high-speed and high-load linear motion applications.

Q: How do the contact seals on both sides of the bearing unit enhance usage?

A: Contact seals on both sides protect internal components from contaminants and help retain lubrication, improving operational reliability, extending service intervals, and safeguarding the bearings lifespan in challenging environments.
