Steering in the future

Steering systems are becoming increasingly more advanced as OEMs designing the next generation of electric and autonomous vehicles that prioritize safety, efficiency, control, feel and precision. Lubricants play an important role in increasing the life, performance, and reliability of the entire steering system. They reduce friction which reduces the amount of power draw on assist motors, extending the driving range of electric vehicles. Grease also reduces heat caused by friction, protects and prolongs the life of components, making them less susceptible to failure. This helps to avoid safety critical issues, warranty claims, and recalls.


Lubricants for Steering Components

Light weight synthetic hydrocarbon greases with advanced additive packages greatly reduce frictional torque between the gearing components. This allows for lower current draw over extended periods of use. They also improve low temperature torque performance, while providing wear protection and vibrational damping. Grease can also be used for its thermal management, corrosion protection, and wear mitigating capabilities.

  • RENOLIT CX-SPS 0
  • Rheolube® 363F*
  • Rheolube® 462CF*

The friction from the junction of the yoke and steering rack can transmit vibrations that are felt by the driver. Yokes require a grease with excellent damping characteristics to minimize noise and vibration. Lubricants thickened with PTFE are ideal for these sliding conditions where good film strength is needed to reduce friction.

  • RENOLIT JP 1619
  • RENOLIT CX-SPS 0
  • RENOLIT LT 2
  • Fluorocarbon Gel 875MS*

If not properly lubricated, couplings, and ball bearings located at the end of the steering column, can transfer noise and vibration through the steering column up to the driver. Greases can quiet these applications and provide durability and wear protection. Load should be considered when selecting a grease. Heavily loaded designs require a heavy viscosity grease to ensure the proper wear prevention and mechanical damping properties.

  • Fluorocarbon Gel 868MS-X *
  • Fluorocarbon Gel 868*
  • Rheolube® 362HB*
  • NyoGel® 774VLF*

For plastic-to-metal interfaces, a medium-viscosity, synthetic hydrocarbon grease enhanced by PTFE ensures good slip and low “stiction.” For metal-tometal interfaces, a heavier synthetic hydrocarbon grease is recommended. A lighter grease designed for sliding surfaces is recommended for tight tolerances between telescoping shafts.

  • RENOLIT ST-XLF 1
  • Fluorocarbon Gel 866*

Rack and pinion designs often feature high loads and tight tolerances. Lubricants formulated with Extreme Pressure additives withstand high loads to reduce friction to prevent wear. A lubricant with good adhesion and low temperature performance is recommended to ensure reliable operation. Plastic and steel compatibility should also be considered.
