LR 5203‑2RS Yoke-Type Track Roller Bearing
The LR 5203‑2RS is a double-row, sealed track-roller bearing (cam-follower / yoke-type) with a crowned outer ring. The “2RS” indicates rubber seals on both sides, protecting the bearing from dust and retaining lubrication. It is suitable for conveyors, guide rails, cam-follower systems, and other machinery where a roller must move along a track under load. The crowned outer ring provides even stress distribution and smooth rolling, ensuring reliable operation in harsh or dirty environments.

LR 5204‑2RS Yoke-Type Track Roller Bearing
The LR 5204‑2RS is a double-row, sealed track-roller bearing (cam-follower / yoke-type track roller) with a crowned outer ring profile. The “2RS” suffix means it has rubber contact seals on both sides, which help retain lubricant and prevent dust or contaminants from entering — making it suitable for conveyors, guide rails, cam-follower systems, or other industrial machinery where a roller runs along a track under load. The crowned outer ring helps distribute stress evenly on the track and reduces wear, contributing to smoother, more reliable operation in harsh or dirty environments.

LR 5205‑2RS Yoke-Type Track Roller Bearing
The LR 5205‑2RS is a double-row, sealed track-roller bearing (cam-follower type) with a crowned outer ring. The “2RS” suffix indicates it has rubber contact seals on both sides to retain lubricant and prevent dust or contaminants from entering, making it suitable for conveyors, guide rails, cam-follower systems, and other industrial machinery where a roller must run on a track under load. The sealed, double-row construction provides stable performance, good load capacity, and reliable rolling even in harsh or dirty environments.
LR 5206-2RS Yoke-Type Track Roller Bearing
The LR 5206‑2RS is a yoke-type track roller (cam-follower) bearing designed for applications where a roller must run on a track or rail under load. It features a double-row construction and is sealed on both sides, as indicated by the “2RS” suffix, which protects the bearing from dust and contaminants while retaining lubrication. The bearing’s crowned outer surface allows it to tolerate slight misalignment or track irregularities, providing smooth rolling motion and enhanced durability. This makes it ideal for conveyors, guideways, industrial machinery, and other equipment requiring reliable track-following rollers in potentially harsh or dusty environments.
SFU 4010-4 Ball Screw Nut
The SFU 4010-4 Ball Screw Nut is a heavy-duty, high-capacity linear-motion component suited for industrial and CNC applications where high load-bearing capability, long travel, and fast linear displacement are required. Designed for a 40 mm diameter screw shaft with a 10 mm lead, each revolution moves the nut 10 mm along the shaft — enabling rapid long-axis movement for heavy loads. The nut’s design includes an internal ball recirculation system (4‑circuit) that ensures smooth, low-friction motion with reduced backlash and enhanced rigidity, even under high loads or during frequent motion cycles. Made from hardened alloy steel, both screw and nut are built for durability and longevity. Its robust dimensions and mounting compatibility make SFU 4010-4 ideal for heavy CNC machines, large‑scale automation equipment, industrial positioning tables, and any application demanding high stiffness, reliability, and efficient linear motion under load.
SFU 2010-4 Ball Screw Nut
The SFU 2010-4 Ball Screw Nut is a precision linear-motion component built for CNC machines, automation systems, and other machinery where accurate, repeatable linear displacement is needed. It works with a 20 mm diameter screw and a 10 mm lead, translating each full screw revolution into 10 mm of linear travel — giving faster traverse compared to lower-lead screws. The nut uses an internal recirculating ball circuit (4‑circuit design) that reduces friction and backlash, improving rigidity and positioning accuracy under load. Constructed from hardened bearing/alloy steel for both nut and screw, it delivers good durability and lifespan even under repeated or heavy-duty use. Its flanged nut design uses a standard mounting arrangement, compatible with common supports and nut‑housings, making SFU 2010-4 a convenient and dependable choice for linear-motion axes in CNC, milling, or automation setups.
