YDTech™ manufacturer of NJ cylindrical roller bearings! supplier of rolling element bearings(NJ) in china.

NJ cylindrical roller bearings are a type of roller bearings that are designed to support high radial loads and moderate axial loads in one direction. The NJ stands for "new jersey," which is the abbreviation for the type of bearing that has a one-piece, separable inner and outer ring, and a cylindrical roller set.

the separable inner and outer rings of NJ cylindrical roller bearings make them easy to install and remove. the cylindrical roller set is made up of cylindrical rollers that are guided by the inner and outer rings. the rollers are arranged in a linear configuration, allowing them to withstand heavy radial loads.

NJ cylindrical roller bearings are commonly used in various applications, such as machine tool spindles, gearboxes, and other precision equipment that requires high accuracy and rigidity. they are available in different sizes, designs, and materials to meet specific application requirements.

cylindrical roller bearings are a type of rolling-element bearing that use cylinders (or rollers) with a slightly modified shape to reduce friction between rotating and stationary components. Unlike needle roller bearings, which have long, thin cylindrical rollers, cylindrical roller bearings have short, thick cylinders that are slightly crowned or tapered to reduce stress concentrations.

cylindrical roller bearings are designed to handle high radial loads, and in some cases, moderate axial loads as well. they are commonly used in applications such as machine tools, rolling mills, electric motors, pumps, and gearboxes.

single row cylindrical roller bearings: these bearings have a single row of rollers, and are capable of handling light to medium radial loads.

double row cylindrical roller bearings: these bearings have two rows of rollers, and are capable of handling heavier radial loads than single row bearings.

full complement cylindrical roller bearings: these bearings have no cage or retainer, allowing for maximum roller capacity and load carrying capability.

multi-row cylindrical roller bearings: these bearings have more than two rows of rollers, and are used in extremely heavy-duty applications, such as large industrial gearboxes.

cylindrical roller bearings are a reliable and versatile type of bearing that can handle a wide range of loads and speeds.
