Product Overview: The MB 31 Lock Washer
The MB 31 is a precision-engineered Lock Washer, an essential component in securing bearings and other mechanical parts onto a shaft. Specifically designed to work in tandem with a KM 31 lock nut, this washer prevents the nut from loosening due to vibration, torque, or other operational stresses. Featuring multiple tabs around its circumference, one tab is bent into a keyway or slot on the shaft, while another is bent into a corresponding slot on the lock nut, creating a secure mechanical lock.
As a key part of our Bearing Accessories range, the MB 31 ensures the safe and reliable mounting of bearings, particularly when used with adapter or withdrawal sleeves. Its robust construction guarantees long-lasting performance in demanding industrial environments. Proper use of a lock washer is critical for maintaining axial preload and extending the service life of the entire bearing assembly.
Key Features of the MB 31
- Secure Locking Mechanism: Utilizes deformable tabs to create a positive lock, preventing the rotation and loosening of the corresponding lock nut.
- High-Quality Material: Manufactured from durable steel to withstand high fastening torques and resist deformation under load.
- Precision Fit: Engineered to standard dimensions for a perfect fit with KM 31 lock nuts and shafts with a 155mm diameter at the seating.
- Vibration Resistance: An effective and simple solution for securing components in machinery prone to high levels of vibration.
- Easy Installation: The tab-locking design is straightforward to engage with basic hand tools.
- Cost-Effective Reliability: Provides a low-cost, highly reliable method for securing critical components, preventing costly equipment failure.
Common Applications
- Industrial Gearboxes: Secures gears and bearings on transmission shafts, preventing axial movement.
