Originally founded to serve the machine tool industry, Gamet has today expanded into other sectors of industry having high precision bearing requirements. These include the coating of materials, photographic emulsions or adhesives, and the printing and packaging industries.
Products Plain Cup The basic single row bearing can be used in light to medium loaded applications, and provides a simple, cost-effective arrangement. It is mounted in conjunction with either a single or double row bearing. As the outer race is free to slide in the housing, the spring force ensures that a constant bearing system preload is maintained despite thermal expansion due to varying temperature conditions.
BENEFITS Specialist design and manufacturing service available to meet your particular requirements Competitive delivery on most sizes Plain Cup G Type Double row bearings offer nearly twice the capacity of the equivalent single row bearing, and are therefore used in more heavily loaded applications. The plain outer race enables this bearing to be used in a 'floating' position to permit thermal expansion.
As such it can replace a P type bearing when additional load capacity is required. G type bearings can be preadjusted to give GE double row bearings.
This is achieved by fitting a spacer between the inner races to give the required assembly end play or preload. When flushed by mounting the offet produces an axial preload that greatly reduces radial and axial deflections from loading. The manufacturer has tables giving the total offset for bearing size and preload grade. The preload is in a range and the amount of inner race interferance on the spindle has an effect. Naturally when the nner race is dialated the offset and thus the preload increases as a trigonometric function of the cone angle.
Precision class angular contact bearings has burnsh marks for points of max eccentricity and lengthy codes marked on their races. Most all over-the-counter precision angular contact bearings come as a packaged pair in "DU" config. Thus the ground-in offset is not only set for the particular preload but the offset is the same for both bearings.

If the bearings have to be separated by spacers then identical length spacers are all that is required of the assembler. Another is precision grade. The tracking error of the spindle axis is a product of the sum of all the bearing errors - which can be many: the roundness and concentriciy of the raceways to the mounting features, the individual ball errors and the way the balls are distributed in the races, the errors of the mounting fits are but the most influential.
There are more. Bearings are tested for tracking error on equipment resolving into sub-microinches and tens of nanometers and traced on a circular graph where the error is represented in radial exaggerations of 10,, , etc.
The trace looks often looks like a potato to me. Many think this quest for ultimate accuracy is far too refined for their simple needs but not so. The total error of a spindle is the sum of the many possible errors present in the bearing system. It's like a household budget: so much for rent, so much for car payment, bar stock, groceres, carbide inserts, utilties, cutting oil, heat, dentist, etc.
If the 0. The object of this excruciating quest is the roundness of the finished product. The most accurate features commonly seen in the general run of machined parts is bearing fits.Gamet Bearings have been manufacturing high precision tapered roller bearings for over forty years in their Colchester factory.
Bearings can be stored for long periods providing packaging is not damaged and the storage area is dry and not subject to extremes of temperature. If this is neglected, temperatures can rise rapidly causing localized overheating and lubricant break-down which can lead to premature bearing failure or inferior spindle performance.
Angular Contact Bearings Gamet Bearings can offer a full range of precision angular contact bearings in most European brands.
Mounting should be undertaken in clean, dry, dust free conditions away from metal working or other operations producing swarf or dust. As such it can replace a P type bearing when additional load capacity is required. This is achieved by fitting a spacer between the inner races to give the required assembly end play or preload.
