Hydraulic seals

Hydraulics Seal Kits

Most of mechanical applications are being performed by using hydraulic cylinders. It is the sealing system, which takes the pressure, thus it becomes the very critical part of the cylinder. Good & perfect sealing system is the back bone of hydraulic application. Our design engineers have developed a unique system to overcome failure modes common to heavy-duty hydraulic cylinders. We have done it by combining advanced seal materials with the most progressive seal profiles. We have successfully developed many hydraulic seals equivalent to international manufacturers. There performance has been very much appreciated by our customers.

We provide various seals for hydraulic application like piston seals, rod seals, dust seals , wipers, guide rings widely used by the industry. We are authorized representative of ROYAL SEALS (www.royalseals.co.in ) for marketing their products in industrial organizations.

We provide seals for hydraulic applications in following industries:-

  • Steel Plants
  • Cement Plants
  • Aerospace
  • Defence
  • Marine Engineering
  • Contsruction And Mining
  • Oil & Natural Gas Exploration
  • Others

Pneumatic seals

Pneumatic Seal Kits

Pneumatic seals are a device that restricts the escape of air or the entrance of foreign materials in a pneumatic application such as a cylinder. Pneumatic Seals are designed for low operating pressure. Pneumatic Seals are vital in machinery. Pneumatic Seals may be used for rotary and reciprocating motion. Pneumatic cylinders typically demand higher operating speeds and lower friction pneumatic seals.

We provide various seals for pneumatic applications like cushion seal, rod seals, piston seals in polyurethane, fluropolymer and nitrile material.We also provide seal kits for various pneumatic applications.

We also serves various industries like:-

  • Steel Plants
  • Automation
  • Textile Equipments
  • Various Other Applications

PU Friction Disc For Texturising Machines

Rotamic offers Polyurethane friction disc for texturising machines. Pu disc are available for all types of texturing machines like BARMAGG, RIETER SCRAGG, HIMSON, ALIDHRA etc. Rotamic PU DISC offer a much higher amount of friction and therefore more twist. As synthetic fibers are normally harder than PU, there is no noticeable fiber abrasion. This results in improvements regarding tenacity and elongation of the textured yarn.


Texturising Industries
Difference between Polyurethane Rubber Soft disc and Ceramic and Plasma coated hard disc:-
  • It offers much higher amount of friction therefore more twist.
  • Softness of PU rubber leads to minimal fiber abrasion and therefore generation of fluff stuff,also known as snow,is prevented during processing.
  • It has better texturing ability and imparts better characteristics like desired bulk,loft and stretch in the yarn.
Rotamic PU friction disc has following special properties:-
  • Very high wear resistance against high speed rotation due to grade of polyol and isocynate.
  • Addition of certain additives makes it more oil resistant,high temparature resistant and safe against electrostatic charge build up.
  • 100% piece to piece dimensional accuracy allows texturisers to have accurate yarn angle while moving through the friction unit.
  • Uniformity and perfection in surface finish of Rotamic disc ensure apropriate T2/T1 ratio from the start itself to throughout its entire service life.
  • Varieties in hardness of PU material allows texturisers to select appropriate disc hardness for different yarn qualities and deniers.
Rotamic offers PU friction disc are available in three hardness for different applications:-
material code shore hardness(a/d) type distinctive color Application
rotamic9045 90/45 hard golden yellow polyamide/polyester high/variable denier yarn
