Our products and services are everywhere. In fact, wherever there is a fluid power seal, there is likely to be a Kroc turning seal product.
To prevent dust or impurities from entering the sealing system, dust seals must prevent the ingress of contaminants under both static and dynamic conditions.
The piston rod seal and the buffer seal can seal the sliding movement between the cylinder body and the piston rod.
Piston seals are used to achieve sealing contact between the piston and the cylinder.
Covers a wide range of radial and axial seals used between rotating and stationary machine parts, or between two parts in relative motion.
It is composed of an energizing spring with load deformation performance and a thermoplastic and fluoroplastic engineering plastic profile. It is widely used in various temperature-resistant, friction-resistant and corrosion-resistant working conditions.
The special design of the static seal is mainly to improve its stability in the groove and avoid distortion during installation.
They guide the piston and piston rod and absorb side loads. They also prevent metal-to-metal contact, which could damage and scratch surfaces.
Prevent seal failure due to extrusion and increase the upper pressure limit. The self-adjusting retaining ring can adjust its fit on the dynamic sealing surface to optimize anti-extrusion performance.
Comprehensive customized sealing ring solutions, supporting a variety of materials and personalized functional designs. Widely used in valves, piping systems, hydraulic equipment, industrial machinery and other fields.
It is mainly used for valve seat seals in oil drilling equipment (such as mud pumps, fracturing trucks, cementing trucks, etc.), and plays the role of water inlet and outlet of one-way valves.
We focus on polymer materials, especially mid-to-high-end raw materials. The consistency of their composition, performance and physical properties will enable seals to achieve the expected sealing effect and life.
High-quality mid-to-high-end raw materials and efficient production management have provided high-performance turning sealing components and professional sealing solutions to global customers for many years.
