The LM 35 UU is a closed‑type linear ball bearing (also called a linear bushing) built to run smoothly along a 35 mm shaft for precise linear motion. It has an inner bore of 35 mm, an outer diameter of 52 mm, and a length (along the shaft) of 70 mm. Inside, it contains six rows of steel balls (ball circuits = 6), held in a plastic (resin) retainer, which roll along the shaft for smooth, low‑friction motion. The bearing’s body is made of hardened bearing steel, and it is sealed on both ends (“UU” = sealed both sides) to keep out dust, dirt, and moisture — reducing maintenance needs and improving durability. Its basic dynamic load rating is high (about 1670 N) and the static load rating about 3140 N, making it capable of carrying substantial loads while still enabling smooth linear motion. Because of its size, load capacity, and sealed design, LM 35 UU is commonly used in medium to large‑scale CNC machines, automation equipment, 3D printers, linear actuators, and other mechanical systems where stable, accurate, shaft‑guided linear motion under load is required.
The LME 25 UU is a closed-type linear ball bearing, also known as a linear bushing, designed to slide smoothly along a 25 mm shaft, providing precise, low-friction linear motion. The “UU” designation indicates that the bearing is sealed on both ends to protect against dust, dirt, and moisture, extending its service life and reducing maintenance. Internally, it contains six rows of steel balls retained in a polymer cage, allowing smooth, stable motion along the shaft. The bearing has an outer diameter of 40 mm, an overall length of 58 mm, and a total width of 44.1 mm. It has a basic dynamic load rating of approximately 980 N and a static load rating around 1570 N, enabling it to support moderate loads reliably. The sealed, closed design combined with hardened steel construction makes the LME 25 UU ideal for CNC machines, linear actuators, automation systems, 3D printers, and other equipment requiring precise, shaft-guided linear motion.
The LME 30 UU is a linear ball‑bushing bearing designed to provide smooth, low‑friction linear motion along a 30 mm shaft. The “UU” designation indicates that it is sealed on both ends with rubber seals to protect against dust, dirt, and moisture, extending the bearing’s operational life. It has an outer diameter of 47 mm and an overall length of 68 mm. Inside, it contains six rows of hardened steel balls held in a resin or plastic retainer, which roll along precision‑ground raceways to minimize friction while supporting the moving load. The bearing’s outer housing is made of hardened steel, giving it strength and rigidity for industrial applications. LME 30 UU is commonly used in CNC machines, 3D printers, automation equipment, robotics, and other machinery requiring stable, precise linear motion on a shaft. Its sealed, closed‑type design makes it particularly suitable for environments where contamination or debris could impair performance.
NK 1212
The NK 1212 is a machined‑ring needle roller bearing without inner ring. Its design assumes that the shaft itself will serve as the inner raceway (i.e. the shaft must be hardened/ground). This makes the NK 1212 very compact, low‑profile and suitable for light weight or space‑constrained applications where shaft treatment is already handled, such as small motors or compact gear assemblies.
NKI 1516
The NKI 1516 is a machined‑ring needle roller bearing with inner ring, providing a hardened raceway independent of the shaft — which means it can be used even if the shaft is not specially treated. It offers excellent radial load capacity while maintaining a compact cross‑section, making it ideal for gearboxes, small motors, and industrial machinery requiring low-profile bearings. The needle‑roller and cage assembly ensures smooth rotation, good rigidity, and reduced friction under load
NKI 2530
The NKI 2530 belongs to the same series of needle roller bearings with inner ring; it is designed for heavier‑duty applications where larger shaft diameter is needed while still offering compact radial space usage. It is suitable for larger industrial gearboxes, conveyors, heavy machinery shafts, and other systems where strong radial load support and compact bearing profile are required.
NKIS 50
The NKIS 50 is a single‑row, machined‑ring needle roller bearing with inner ring, designed for applications where radial space is tight but high radial load capacity and stability are required. Its dense complement of fine rollers guided by a steel cage — combined with a sturdy outer ring with flanges — delivers excellent stiffness, smooth rotation, and even load distribution under heavy-duty or continuous operation. Because the bearing comes complete with its own inner ring, it's a suitable choice in situations where the shaft surface isn’t hardened or ground to function as a raceway, ensuring proper bearing seating, easier installation, and long service life when properly lubricated.
NA 4900
The NA 4900 is the smallest standard machined‑ring needle roller bearing with inner ring in the “NA 49..” series, designed for very compact, low‑cross‑section radial load applications. Its small dimensions make it suitable for precision assemblies, small motors or pumps, and wherever minimal space and light loads are involved. Despite its compact size, it retains the typical advantages of needle roller bearings: high radial load capability relative to its size, smooth rotation, and reliable performance with proper lubrication.
NA 4901
The NA 4901 is a single‑row needle roller bearing with machined rings and an inner ring, featuring outer ring flanges for guidance. It delivers high radial load capacity while keeping a low cross‑sectional profile — well suited for compact mechanical assemblies, small gearboxes, and lightweight industrial equipment where space is constrained but load demands exist. The needle‑roller configuration gives reliable, smooth rotation and good rigidity under load, and its steel construction ensures durability and a long service life.
NA 4902
The NA 4902 is a single‑row needle roller bearing with machined rings, flanges on the outer ring, and an inner ring — designed to deliver high radial load capacity while maintaining a low cross‑sectional height, making it ideal for assemblies where radial space is limited. Its compact form factor and dense arrangement of fine rollers ensure smooth, precise rotation, high stiffness, and reliable load distribution under continuous or heavy-duty conditions. This bearing is commonly used in gearboxes, pumps, alternators, and other mechanical systems needing durable performance and efficient operation.
NA 4903
The NA 4903 is a single‑row needle roller bearing with machined rings and an inner ring, designed to deliver high radial load capacity while maintaining a low cross‑sectional profile. Its dense pack of needle rollers gives it high stiffness and excellent load distribution, making it suited for gearboxes, pumps, small motors, and other compact mechanical assemblies where space is limited but reliability is critical. The outer ring includes two integral flanges for axial guidance and typically features lubrication groove/holes to support maintenance and smooth operation under continuous load.
