Kinematics slewing bearings are a cost-effective design and performance enhancement option for rotary devices carrying heavy loads.

Slewing rings have a compact design, which facilitates more ease of use and can be manufactured without teeth, with internal or external teeth, with balls and/or with rollers. The patented hourglass design of Kinematics' slewing ring bearings is especially effective. The design of their slewing rings allows more teeth to be engaged at one time, leading to higher torque endurance and, essentially, a stronger and more durable slewing bearing.

The slewing bearing drives in heavy machinery enable higher torque, speed reduction and rotational functions. Applications include solar trackers, digger derricks, truck cranes, wind turbines, utility equipment, hydraulic equipment attachments and tire handlers. Their range of applications make slewing ring bearings an integral part of particular industries, including aerospace, automotive, forestry, manufacturing, medical, military, nautical, power, robotics and surveillance.

Here's a look slewing bearings in a few different industries:

Slew Bearings for Truck Cranes

Slew Bearings for Truck Cranes

Cranes are uniquely constructed, which means the slewing ring bearing is an essential element of its design. Quality and precision during the manufacturing process are vital to make sure the crane will run after it's been dismantled and reassembled.

Slew Ring Bearings for Medical Industry

Slew Ring Bearings for Medical Industry

Slewing rings in a medical environment need to be highly precise and expertly constructed when it comes to the rings and rolling elements. Slewing bearings must also have some type of sealing solution to prevent leakage in a sterile environment.

Slew Bearings for Forestry Industry

Slew Bearings for Forestry Industry

The components of forestry equipment must be strong and durable. The rugged environments they operate in require a design and holding capacity that can withstand the elements. That means that their slew bearings must be able to operate in conjunction with the high rotating speed of the de-barkers and in cold temperatures.
