Trelleborg acquires North American precision seals company

Trelleborg, through the Trelleborg Sealing Solutions business area, has acquired the operations of precision bearing and sealing devices company Hydro-Components Research & Development Corporation (HCRD). The company employs a total of approximately 80 people and has annual sales of about SEK 50 million. It is a privately owned company based in Streamwood, Illinois, USA.

HCRD, which manufactures high-precision components, focuses specifically on large diameter seals and bearings. These products are used primarily in applications involving heavy-duty cylinders such as shock absorbers for earth moving equipment, dumpers and diggers.

“HCRD’s technology and products are at the leading edge of development in the company’s area of focus and will make an extremely valuable contribution to us,” says Claus Barsøe, Business Area President for Trelleborg Sealing Solutions. “The products fit in ideally with our current portfolio, will expand our offering and enable us to grow more rapidly in North America, within the segment for heavy duty vehicles. The acquisitions also offer distinct process and organizational synergies.”

Trelleborg Sealing Solutions has annual sales of approximately SEK 5.4 billion, with some 5,600 employees. It has production units in Brazil, Canada, China, Denmark, France, India, Italy, Japan, Malta, Mexico, Poland, Sweden, the UK and the US.

Materials:

Hydro-Components 1903 is now HM803:Reinforced Nylon 6 with 40% Glass Fill

Hydro-Components 1952 is now HM852: Nylon 6 Glass Fiber-Reinforced (40%) with PTFE

Additional materials are available for custom applications.

Wear Rings

Trelleborg Sealing Solutions Streamwood was the primary supplier of wear rings to one of the world’s largest manufacturers of earth moving and heavy duty construction equipment. These applications experienced operating pressures and temperatures of 4,500 psi and 93°C, respectively. During this eighteen year partnership, there was not a single wear ring related warranty claim reported.

Our manufacturing capabilities have enabled hydraulic cylinder builders to increase their productivity and improve the quality of their product by replacing multiple, narrow-width wear rings with a single wide wear ring to fill larger gaps.

Our material is 25 percent stronger in terms of compressive strength than any of our competitors’ comparable materials.

• Imbeddable nylon material that is special for wear ring applications
• Proprietary 40 percent glass reinforcement fibers provide maximum compressive strength
• We injection mold for maximum density and compressive strength, and then precision machine to size
• Quality is assured through SPC and ISO 9001 / 2000
• Ultra-tight tolerance machined wall dimension available to +/- 0.0005
• Helps to protect your system hardware and prevent contamination failures
• Provides you with additional compressive strength that has been proven in the toughest applications
• You get the highest performing material, precision machined to provide optimum performance
• Consistent high performing wear rings
• Improves seal life and allows higher operating pressures

Solid & Split Bearings

• Higher compressive strength than bronze SAE 660
• Self–lubricating
• Does not contain lead
• Noise Reduction
• Weight savings
• Imbeddable material
• Tight tolerance machining
• Quality is assured through SPC and ISO 9000 / 2000

Wear Pads

We were able to replace the bronze wear pads on a motor grader resulting in weight reduction and cost savings. We were successful in replacing aluminum/bronze pads on injection molding machines resulting in weight reduction, extended life and cost savings.

We were able to replace a nylatron part on the side shift mechanism of a forklift application. This resulted in reduced maintenance, maintenance cost savings and extended life by a factor of two to three.

• Imbeddable nylon material that is special for wear applications
• We injection mold using proprietary 40 percent glass reinforcement fibers that provide maximum compressive strength
• Tight tolerance machined surfaces that are flat
• Quality is assured through SPC and ISO 9000 / 2000
• Many sizes already available
• Internally lubricated
• Helps to protect your hardware from damage due to foreign particles
• Twice the strength of Cast or ExtrudedNylon materials used by machine shops
• Improves the performance of your wear pad providing your customer with more up time
• Consistent high performing wear pads
• May eliminate or reduce set up charges
• Assures smooth operation of your equipment

Hydrolock Guidelock Assemblies Metric-Piston

• Hydrolock Bearing made from TSS HM803 material
• Redundant Seal Surfaces
• Combination of high pressure and low pressure sealing elements
• High pressure seal elements are made from TSS HM803
• Low pressure seal elements are made from heat stabilized glass reinforced Hytrel®
• Quality is assured through SPC and ISO 9000 / 2000
• Innovative Reliable Design
• Prevents metal-to-metal contact between the piston and the bore
• Zero Drift
• Assures zero leaks at a wide range of operation conditions
• Provides excellent high pressure sealing and supports the low pressure sealing elements
• Softer material conforms to the rod to assure a dry rod
• Consistent high performing seals
• Proven for injection molding, presses, mining, industrial and off-road

Thrust Washers

We supplied thrust washers made from high temperature nylon family materials for planetary transmission applications in off-highway construction equipment. We replaced a part resulting in cost savings and increased durability.

In another instance, we replaced bronze thrust washers with parts made from HM803 on backhoe loader and agricultural tractor applications. This change resulted in weight reductions and cost savings.

• Surface profiles are super flat and parallel
• Imbeddable nylon material that is excellent for thrust washer applications
• We injection mold using proprietary 40 percent glass reinforcement fibers that provide maximum compressive strength
• Quality is assured through SPC and ISO 9000 / 2000
• Complex or simple shapes
• Helps to protect your hardware from damage due to foreign particles
• Twice the strength of cast or extruded nylon materials used by machine shops
• Consistent high performing wear pads
• We work with you to design a part to optimize performance and reliability

Zero Gap Piston Seals

• An operating temperature range from –40°F to + 275°F
• Pressures to 5,000 PSI
• Interchangeability with most piston and expander rings now used. Retrofits all C914 piston seals.
• Extended seal life
• Imbeddable material using HM803 or HM852 materials
• Easier assembly
• Port passing capabilities, including hydraulic cylinders with a series of cushioning ports
• Quality is assured through SPCand ISO 9000 / 2000
