61888-M

The 61888-M is a high-precision, single-row deep groove ball bearing designed for applications where space is limited and high rotational speeds are required. As part of the extra-light 618 series, this bearing features exceptionally thin cross-sections for both its inner and outer rings, making it significantly lighter than standard bearings of the same bore diameter. The "M" suffix indicates a solid brass cage, which is roller-guided. This robust cage design offers superior performance and durability, especially under high-speed, high-temperature, or high-vibration conditions. The 61888-M is engineered to accommodate radial loads and moderate axial loads in both directions, offering versatile performance in a compact footprint.

The primary advantage of the 61888-M bearing lies in its space-saving and weight-reducing design, which allows for more compact and lighter machinery construction without sacrificing load-carrying capacity. The solid brass cage provides enhanced operational reliability, generating less friction and heat than other cage materials, which contributes to a longer service life and extended maintenance intervals. Its suitability for high-speed operation makes it an excellent choice for precision instruments, robotics, electric motors, and other specialized equipment where both rotational accuracy and a minimal footprint are critical design criteria. The bearing's straightforward, non-separable design simplifies both mounting and maintenance procedures.
