ST 254055 B
The ST 25 B is a compact linear ball bushing designed for smooth, low‑friction linear motion along a 25 mm diameter shaft. With a 25 mm bore, 40 mm outer diameter, and length of 55 mm, it offers a small‑footprint yet dependable solution for linear guide systems, CNC machines, automation equipment, and other mechanical setups requiring precise, repeatable linear travel. Inside the bearing sleeve, rows of hardened steel balls circulate to provide smooth, accurate sliding motion with minimal resistance, which helps extend shaft and bearing life. With a dynamic load capacity around 3,600 N and a static load rating near 4,700 N, ST 25 B is suitable for light to moderate loads and frequent motion cycles. Its compact size and modest weight make it ideal for applications where space is limited but reliable linear motion is essential.
ST 304565 B
The ST 30 B is a durable linear ball bushing designed for smooth, low-friction linear motion along a 30 mm diameter shaft. With a 30 mm bore, 45 mm outer diameter, and 65 mm length, it provides a compact yet robust solution suitable for CNC machines, automation equipment, linear guides, and other mechanical systems requiring precise and stable linear travel. Its construction features multiple rows of hardened steel balls that circulate within the sleeve, ensuring smooth and accurate linear motion with minimal resistance. The ST 30 B supports moderate to heavy loads with a dynamic load capacity of approximately 4,800 N and a static load rating of about 6,270 N. Lightweight and compact, it is ideal for guiding 30 mm shafts in tight layouts, providing reliable, efficient, and long-lasting performance in industrial and mechanical applications.
ST 352570 B
The ST 35 B is a robust linear ball bushing designed for smooth, low‑friction linear motion along a 35 mm diameter shaft, combining compact form factor with dependable load-bearing capacity. With an inner diameter of 35 mm, an outer diameter of 52 mm, and a 70 mm bushing length, it offers a balanced design ideal for linear guides, automation equipment, CNC machines, and other mechanical systems requiring precise and stable linear travel. Its construction supports both moderate dynamic and static loads, making it suitable for applications where repeated motion and moderate loads are expected. The ST 35 B ensures smooth sliding motion, reduces friction compared to plain bushings, and maintains shaft alignment — contributing to longevity and reliability in linear motion setups. Its compatibility with standard 35 mm shafts makes it a versatile choice for retrofits or new builds where linear motion is required.
ST 406080 B
The ST 40 B is a linear motion ball bearing (linear bushing) designed for smooth, low‑friction sliding along a 40 mm shaft in automated and mechanical systems. With an inner diameter of 40 mm, outer diameter of 60 mm, and a robust 80 mm length, this bearing provides stable support and precise linear travel for applications such as CNC machines, linear actuators, guides, and automation equipment. Made from hardened chrome steel, ST 40 B offers good durability and resistance to wear under continuous or repetitive motion, while its dynamic and static load ratings ensure it can sustain considerable loads without compromising performance. Its compact cylindrical shape and moderate weight make it easy to integrate into linear motion systems, offering a reliable and cost-effective solution for guiding shafts, rails, or rods in industrial or DIY setups.
The LM80UU is a heavy-duty linear motion ball bearing designed for smooth, accurate, and low-friction movement along an 80 mm precision shaft. Built from hardened bearing steel, it features multiple recirculating ball circuits that provide excellent load capacity and rigidity, making it ideal for industrial automation, CNC machinery, packaging systems, and heavy linear motion equipment. Its double-sealed “UU” design helps keep dust and contaminants out, ensuring long life and reliable operation even in demanding environments. With its large inner diameter and robust construction, the LM80UU delivers stable, precise linear travel for high-load and long-stroke applications.
