Inner Rings
Standard Performance Inner Rings are characterized by their smooth inner surface, also they usually do not have any special features. This simple and reliable structure provides a solid base for needle rollers and is used in most applications.
Inner Rings with Lubrication Hole are special inner rings for needle roller bearings used in areas with high loads. These inner rings are equipped with targeted lubrication holes that enable direct lubrication of the needle roller bearings and thus increase their service life.
Inner Rings Free from Spiral Marks feature a unique surface structure that ensures precise guidance of the needle bearing rollers and effectively minimizes skewing. This design is used primarily in sectors where high accuracy standards are required.
Raceway Rings have a specific surface structure to reduce friction between the inner ring and the shaft. They are often used in combination with needle bearings, which are subjected to high loads and speeds. Raceway rings can be made of various materials such as plastic, bronze or stainless steel.
