Product Information

Smalley bearing preload Wave Springs eliminate play and minimise bearing noise. The constant light/medium pressure they apply removes play between the ball bearings and the bearings™ inner and outer races. Preloading can reduce the possibility of bearing damage due to vibration (vibratory loading) and wear due to repetitive and non-repetitive run out.

Materials: Carbon steel and 17-7 PH/C stainless steel. Alternative materials are available on request.

Quality assured since 1981 ISO 9001:2008 Aerospace AS9100C & AS9120AWith ISO9001: 2015 approval incorporating Design Status, our qualified engineering staff are able to offer a completely free of charge engineering service and are available to assist with part selection, custom design, application requirements, material selection and more.

Applications are discussed in-depth, first-off design data and drawings are submitted for approval to ensure our customers are provided with the correct design, first time. However, on those rare occasions when modifications are necessary, our no-tooling process and flexible manufacturing procedures means the production of prototypes is easily and economically achieved without onerous tooling charges and long lead times.

At TFC we realise that Quality runs through the entire business, not just our products. We have continually invested in the right people to provide the superior market knowledge and customer service.

In mechanical engineering, ball bearings play a pivotal role by facilitating unhindered movement and minimising friction. These intricate components are meticulously crafted to integrate multiple parts into a harmonious unit, resulting in efficient motion transmission. Nonetheless, the complex manufacturing and assembly processes can occasionally introduce challenges, particularly in scenarios involving heavy loads.

Engineers and manufacturers have turned to a robust preloading solution to counter the potential limitations posed by the manufacturing and assembly process. Preloading involves applying a consistent axial load to a bearing, effectively elongating its lifespan and subsequently enhancing the overall performance of the equipment it serves.

What are Bearing Preload Springs?

Solid preloading entails anchoring inner and outer races with a locking mechanism, ensuring a secure and controlled arrangement. Conversely, spring preloading, the more straightforward and cost-effective method, employs springs to apply a continuous axial load, effectively mitigating variations caused by external factors. This is precisely where Smalley bearing preload springs step in, offering enhanced effectiveness and the added benefit of controlling play to maintain bearing functionality and longevity.

Advantages of Bearing Preload Springs

Maintaining consistent contact between bearing components becomes attainable with the correct bearing preload spring. This critical achievement eradicates both radial and axial play, delivering an array of benefits that extend beyond the realm of mere mechanics. The ingenious design of these springs ensures minimal pressure on the ball bearing, mitigating unnecessary wear and tear and fostering extended operational life.

As a distinguished supplier of springs, TFC proudly stands as the sole provider of Smalley wave springs and bearing preload springs in the UK. Our extensive array of bearing preload springs caters to diverse applications and dimensional requirements, ensuring an impeccable fit for various engineering scenarios.

Crafted from cutting-edge materials and technology, the bearing preload springs supplied by TFC epitomise unwavering quality. These springs are thoughtfully engineered to fit seamlessly within confined spaces, allowing manufacturers to optimise equipment design for compactness and high performance, all while upholding safety and longevity.

In high-precision and high-speed applications, the value of bearing preload springs becomes even more apparent. These springs bolster equipment resilience and durability by eliminating the need for exceedingly tight tolerances, thereby accommodating rigorous operating speeds without compromising efficiency.

TFC’s bearing preload springs boast a distinctive wave design that facilitates optimal load distribution between bearing components, effectively reducing wear and tear. This innovative design also translates to quieter operation, even in high-vibration environments, ensuring a seamless user experience.
