The characteristics of splines are

The trapezoidal spline nut is formed by low-cost special alloy die-casting, using high-precision spline shaft as the core. These are different from traditional machined products, as their sliding surfaces maintain the cold cast layer formed during the die-casting process, thus achieving high wear resistance.
How to lubricate sliding splines?
Suggest lubricating the spline nut. Oil and drip irrigation are very effective. Oil lubrication is suitable for various conditions, such as high speed, heavy load, or situations that generate high heat. It is the best lubrication method because the nut will be cooled. Drip irrigation lubrication is suitable for medium or low speeds, medium or light loads. For infrequent low-speed movements, lubricating grease can be added to the shaft regularly or the oil holes on the nut can be used for lubrication.
What grease can be used to lubricate sliding splines?
Lubricating grease or molybdenum based grease can be used.
Can sliding spline shafts and nuts be surface treated?
The spline shaft can be surface treated, but the spline nut cannot be surface treated.
What are the materials of the shaft and nut?
All models of trapezoidal spline shafts are made of S45C, and the nuts are made of special zinc alloy.
What measures can be chosen to prevent dust?
Because there are no sealed protective components on the trapezoidal spline, customers can use a dust cover to prevent dust.
