UNIQUELY EFFECTIVE BEARINGS

DUROBAL®: UNIQUELY EFFECTIVE BEARINGS Durobal® rolling element bearings are ideally suited for use in a wide variety of industries and applications. Trelleborg Sealing Solutions has already helped thousands of customers to achieve their goals through innovative thinking and in-depth knowledge. Medical - Bearings to rotate MRI machine Challenge: Magnetic Resonance Imaging (MRI) equipment is used to make images of soft body tissues. Included in the design of a major MRI maker’s equipment was a table with a 360-degree range of motion. Because it operates in a very strong magnetic field, the table's...

industrial/business machineChallenge: When a leading automated tellermachine (ATM) manufacturer was experiencing unacceptable noise levels due to the metalball bearings installed in its ATM-machines, the company turned to Trelleborg Sealing Solutions for anoise reduction solution. The design engineers evaluated the application, manufacturing capabilities and customer requirements resulting in a recommendation of Durobal® roller element bearings in Turcite® A, a proprietary thermoplastic material. Using Durobal®, the customer was able to substitute a light weight, non-metallic bearing component,...

DUROBA L®: UNIQUELY EF F ECTIVE BE A RINGS More than just a bearing Trelleborg Sealing Solutions is an expert, not just in seals, but in bearings too. Its unique Durobal® rolling element bearing is ideal for high speed, low-load applications and being constructed of plastic, offers significant advantages over traditional metal components. Most importantly, Durobal® has the added benefit that it can be designed as a single bearing and sealing element that often consolidates a number of components. This can lower total cost, improve integrity and enhance overall product performance, providing you...

BENEFITS OF DUROBAL® ROLLING ELEMENT BEARING SOLUTIONS: Polymer versus metal-ferrous Inner ring configurations Outer Ring The static part of the bearing pressed into the housing – usually constructed of an acetal base material. Self-lubricating, environmentally-friendly Low-friction Molded to consolidate component parts Materials compatible with virtually all media, both system and cleaning • Light-weight with good strength and stiffness • Suitable for magnetic applications Designed for a specific application • Achieves bearing function that is impossible with standard products • Fits into difficult...

Conrad bearing Full Complement bearing The most common ball bearing design. A version of the radial ball bearing, it contains a snap-in cage and deep groove races. A quieter bearing capable of handling higher speeds and lower loads. An extra deep bearing containing no cage but a full complement of balls. Can be used as a pure radial bearing or combined radial thrust bearing. Can carry higher loads at lower speeds. Double/ Multiple Roll Ball Radial Durobal® For use when radial loading is relatively high. It effectively doubles the dynamic load capacity of the bearing compared to a single row bearing....

COMPLEX DESIGN FOR OUTSTANDING PERFORMANCE The Durobal® bearing consists of an outer ring, inner ring, shield, seals and rolling elements held in a cage. The configuration of Durobal® can be varied to meet customer requirements and optimize the performance of an application. Outer ring designs Inner ring configurations The custom Durobal® design allows the table to move in/out and laterally on the machine’s bearing surface. This smooth table movement provides added comfort and extra security to the patient during MRI procedure
