Rod seal

Our slewing bearing’s large, open inner race diameter provides system design flexibility, allowing you to easily incorporate them into your current applications. Furthermore, our bearings can be seamlessly integrated into a slewing drive, taking advantage of Cone Drive’s extensive gearing expertise.

MD-L profiles have a nitrile rubber sealing element with polyester thermoplastic elastomer anti-extrusion rings, which incorporate polyacetal guide rings. The sealing element serves as a slide ring and also seals statically against the seal groove. The anti-extrusion rings support and protect the sealing element against gap extrusion. Both the guide and anti-extrusion rings are split to ease installation. MD-L profiles are suitable for pressures for pressures up to 250 bar (3,625 psi) and are available in metric and imperial sizes. Some metric sizes fit seal housings in accordance to ISO 6547.

Piston Seal additive

Yes, however a WEA or WEB version is recommended when mounting in this orientation for additional corrosion protection. Please contact ae@conedrive.com for more information.

Pneumatic piston seal

Yes, when mounting the slew drive horizontally, it is always recommended to mount the drive with the housing on top and seals on bottom, when possible. When mounting vertically, it is recommended to mount in the worm over orientation

At Cone Drive, we understand the importance of weight and performance optimization. That’s why our low-profile designs are engineered to be lightweight, without sacrificing performance.

Wiper seal

For applications driven by an electric motor, Cone Drive offers a double reduction slewing drive to provide a clean, efficient solution.

Cone Drive’s slew drive technology provides a large ratio in a single gearing stage.  The slewing drives are assembled into a low profile, self-retaining, and ready-to-install housing, optimized for weight and performance.  Our highly adaptable slew gearing features strong shock resistance, long life performance, and smooth rotation.

Differential pressures acting on the piston to extend or retract the piston rod can be in excess of 400 bar (5,800 psi). The pressure acting on the piston seal increases contact forces between the piston and cylinder surface. Therefore the surface properties of the sealing surfaces are critical to proper seal performance.

Designed to fit imperial o’ring housings in accordance to ISO3601 (BS1806/AS568A o’ring sizing), T-seals are an ideal replacement for o’rings. The T-shaped sealing element serves as a slide ring that’s highly resistant twisting and spiral failure. Piston T-seals seal statically against the groove ID and are suitable for pressures up to 345 bar (5,000 psi).

Piston seal types

MPT profiles have a nitrile (NBR) rubber sealing element and hard polyamide anti-extrusion rings that lock into the rubber sealing element.

Piston seals are typically classified into single acting (pressure acting on one side only) and double acting (pressure acting on either side) seals.

GH and GHM profiles have a nitrile (NBR) rubber o’ring energiser and a bronze filled PTFE sealing element. Square ring and Viton energiser are available on request. There profiles are suitable for pressures up to 400 bar (5,800 psi) and are available in metric sizes. Some metric sizes fit seal housing in accordance to ISO 7425-1.
