The DL 4020 RICH is a needle roller bearing without an inner ring (40x48x20 mm) featuring a cageless design for maximum load capacity in an ultra-compact drawn cup structure.
The DL 4020 RICH is a robust needle roller bearing without an inner ring, manufactured by RICH to deliver maximum static and dynamic load-carrying capability within a highly compact design. This unit features precise metric dimensions of 40 x 48 x 20 mm.
This bearing utilizes a cageless design, which allows it to hold the maximum density of needle rollers possible. This construction is specifically engineered for handling extremely high radial loads and is the ideal choice for applications operating at low speeds, under high stress, or involving oscillatory motion. The thin-walled, drawn cup outer ring is intended for secure, interference-fit installation directly into the housing bore. As an inner-ringless bearing, the DL 4020 RICH requires that the mating shaft surface be appropriately hardened and ground to serve as the inner raceway, ensuring structural rigidity and optimal space efficiency in the final assembly.
