PB 6
The PB 6 is a miniature spherical plain bearing designed for small-shaft applications where compact size and smooth rotation with angular accommodation are required. With a 6 mm bore, 18 mm outer diameter, and 9 mm width, PB 6 is ideal for very compact linkages, small actuators, or light mechanical pivots. It supports a dynamic radial load of approximately 4.3 kN and a static radial load of around 9.8 kN, sufficient for light-load conditions or delicate link mechanisms. The bearing’s hardened inner spherical ring and durable outer ring provide reliable sliding contact and resistance to wear, even during repeated cycles of motion. PB 6 is especially useful for small-scale automation, mechanical linkages, or lightweight pivot joints where space is limited but smooth, stable movement is critical.
PB 8
The PB 8 is a small spherical plain bearing suitable for light to moderate radial loads and small-shaft applications. With an 8 mm bore, 22 mm outer diameter, and 12 mm width, it fits in tight spaces while offering reliable rotational and angular motion. It supports a dynamic radial load around 6.8 kN and a static radial load near 16 kN, making it appropriate for small linkages, hinges, or pivot points in machinery, automation systems, or light mechanical assemblies. Its steel outer ring and hardened inner spherical surface provide durability and stable sliding contact, even under repeated motion. PB 8 is particularly useful where compact size and smooth pivoting under load are needed.
PB 10
The PB 10 is a compact spherical plain bearing designed to allow smooth rotational and slight angular motion between a shaft and housing while supporting moderate radial loads. With a 10 mm bore, 26 mm outer diameter, and 14 mm width, this bearing is suitable for small to medium-sized mechanical linkages, pivots, or oscillating joints. Its steel outer ring combined with a hardened spherical inner ring ensures durability and wear resistance under load. PB 10 is well-suited for light machinery, linkage systems, pneumatic or hydraulic actuators, or any mechanical system where compact spherical plain bearings are required.
PB 18
The PB 18 is a robust spherical plain bearing designed to accommodate both rotational and angular motion while supporting substantial radial loads. With an 18 mm bore, 42 mm outer diameter, and 23 mm overall width, it offers a compact yet sturdy profile suitable for mechanical linkages, pivots, suspension arms, and oscillating components. Its spherical inner design allows tilting or angular misalignment up to approximately 15°, making PB 18 especially useful in assemblies where alignment varies during motion. Constructed from high-carbon steel and bearing-grade materials, PB 18 provides high strength and durability under demanding operational conditions. With a dynamic load capacity of around 25,700 N, this bearing is ideal for heavy-duty applications where reliability, smooth articulation, and resistance to wear are required, such as in agricultural machinery, industrial linkages, hydraulic systems, and mechanical suspension components.
The MGN 12 C is a narrow-width miniature linear guide block from the MGN series, designed for compact and precise linear motion applications. It runs on a 12 mm wide rail, with the carriage block approximately 27 mm wide and an assembly height of about 13 mm. Its light weight, roughly 0.03–0.034 kg, makes it ideal for small machinery and devices where space is limited.
The block uses a Gothic-arch contact geometry for its ball bearings, providing good stiffness and rigidity and allowing it to withstand loads from multiple directions, including moment loads, despite its small footprint. The balls are retained in a cage, keeping them captive even if the block is removed from the rail, which simplifies assembly and maintenance.
Because of its compact size, low weight, and smooth low-friction motion, the MGN 12 C is well-suited for applications such as 3D printers, small CNC machines, robotics, measuring instruments, and other miniature automated systems where precision and space efficiency are more important than heavy-load capacity.
The MGN 15 C is a miniature linear guide block from the “MG” series, designed for light- to moderate-load precision applications. Its compact, narrow design makes it ideal for equipment where space is limited, such as 3D printers, light-duty CNC machines, robotics, and measuring instruments. The block features a Gothic-arch contact geometry that provides high stiffness and rigidity against moment loads from all directions while keeping size and weight minimal.
The MGN 15 C has a block width of approximately 32 mm, a height of about 16 mm, and runs on a 15 mm wide rail. Its lightweight design, around 0.06 kg, reduces inertia, making it easier to drive with low-power motors or actuators. The block uses rolling steel balls retained by a cage, which ensures smooth, low-friction motion and prevents ball displacement during assembly or maintenance.
Overall, the MGN 15 C combines a compact footprint, good rigidity, low weight, and smooth linear motion, making it well-suited for small or lightweight automated systems where precision and space efficiency are essential.
