How do you spring preload a bearing?
There are two main methods to preload a bearing. The first is solid preload, which is achieved by holding inner and outer races in place with a locking mechanism. The more common, simpler, and less expensive method is spring preload, which is achieved by using a spring to apply a constant axial load on one side.
What is a preload on a bearing?
Bearing Preload is the process of adding a sustained axial load, independent of external loads, to a bearing. Properly preloading a bearing can increase its life and eliminate the vibration and noise that results from specified clearance, manufacturing precision, and wear.
Do bearings need preload?
Deep groove ball bearings can be preloaded, but it is not required in most applications. The amount of preload applied is important. It must be sufficient to reduce the excess play, but care must be taken not to apply too much preload.
Why do we preload bearing?
The purpose of preload in a bearing system is to eliminate clearance that is designed into standard ball bearings. Almost all radial ball bearings are made with a clearance or space between their components to allow for free movement.
What is spring preload?
Preload is a measurement of how much a spring is compressed at full extension of the shock. Thread the upper spring adjuster down until it just touches the spring, you are now at 0″ of preload. Every inch you thread it down from there is 1″ of preload. If you want less lift then you need softer springs.

How do you use preload?
Easy Ways to Determine Bolt Preload
- Use a Torque Wrench to Reach Optimal Torque.
- Use Preload Indicating Washers.
- Use Direct Tension Indicating Washers.
- Use Silicon Direct Tension Indicating Washers.
- Tighten Until Snug, and Then Tighten “X” Degrees.
Does spring preload affect ride quality?
See all 9 photos Here, spring height’s been adjusted roughly one inch, introducing more preload (top), but since it’s a linear-rate spring, it won’t affect handling or ride quality—just ride height. The exceptions: Go buck wild with introducing preload and it’s possible to muck up suspension travel, though.
How do you find the preload of a bearing?
The simplest method of applying preload is to use a wave spring. The spring acts on the outer ring of one of the two bearings. This outer ring must be able to be axially displaced. The preload force remains practically constant, even when there is axial displacement of the bearing as a result of thermal elongation.
How is preload adjusted?
There are basically two principal methods to adjust preload: individual adjustment and collective adjustment. With individual adjustment, each bearing arrangement is adjusted separately using nuts, shims, spacer sleeves, crush sleeves, etc.
Why use a preload spring for bearing preload?
Using a spring for preload is critical for high-precision or high-speed applications, as it essentially eliminates the need for holding tighter tolerances and helps withstand high operating speeds. Ball complement and bearing races mate reliably and take up dimensional variation. Greater load sharing between bearings due to wave design.
How do you preload a ball bearing?
Figure two illustrates a solid preload applied mechanically to two radial ball bearings. A spring preload is created using a coil spring or a spring wave washer applying a constant axial load to the inner or outer rings.
What is spring preloading with wave washer?
Spring preloading with wave washer; Source: Smalley In spring preloading, sometimes referred to as constant pressure preloading, an axial force is applied to the non-rotating inner or outer bearing ring by spring. Wave springs, coil springs, Belleville springs (washers) and finger springs can be used.
What are the different types of rigid preload?
Other terms for rigid preload include fixed constraint preload and position preload. Spring preloading with wave washer; Source: Smalley In spring preloading, sometimes referred to as constant pressure preloading, an axial force is applied to the non-rotating inner or outer bearing ring by spring.
