Ordering a cylinder according to drawing
OOO KRPMS offers design and production of hydraulic cylinders to order, as well as production according to customer’s drawings.
Production of hydraulic cylinders to order is our main focus, technically we are able to manufacture products with the following parameters:
- piston diameter from 50 to 1,000 mm;
- rod diameter from 20 up to 600 mm;
- rod stroke up to 16,000 mm;
- maximum testing pressure - 70 MPa;
- operating temperature from +250 to -55°С.
The components used for production of hydraulic cylinders ordered according to a drawing:
- Honed cylinder tubes – cold drawn seamless tubes manufactured in accordance with EN 10305-1 (DIN 2391). Standard grades of steel St52, St52BK are used, with a diameter tolerance H8 and roughness of the inner surface up to Ra 0,22.
- Chrome-plated rods can be made of standard steel grades CK45, CK50 with an outer diameter tolerance F7. And also from special grades: 45MnV6, 45MnV1, 38MnVS6, 42CrMo4. The hardness of the chrome surface is from 66 to 69HRC, the thickness of the coating is from 15 μm to 20 μm (depending on the rod diameter). Maximum surface roughness is Ra0.2.
- All types of sealing elements for hydraulic cylinders: wiper seals, piston seals, rod seals, symmetrical, static seals, supporting and guiding rings.
If the parameters of the elements are standard and they can be selected from those available, then the sealing elements manufactured by Aston and Kastas are used.
In case of irregular dimensions or unavailability we manufacture the seals by method of turning on machines made in Austria using raw material from Seal Maker Produktions-und Vetriebs GmbH.
A wide range of materials for sealing elements allows us to manufacture components that can endure loads up to ...
