X-LUBE® BUSHES

suitability PV Calculation

Pressure x Velocity (PV) Values The life of an X-Lube® bush is determined by both pressure and velocity, as well as other environmental factors. This PV value relates to the maximum pressure and velocity that an X-Lube® bush can sustain in a normal working environment. The higher the velocity, the lower the pressure; the higher the pressure, the lower the velocity, as can be seen in the accompanying graph. PV values are intended as a guide only, when determining whether an application is suitable for the use of an X-Lube® bush.

Pressure is assumed to be uniformly distributed over the projected area of the bearing and in the illustration below is equal to:-

×10 N/mm 2 P= W  L× d where: W = kg L = mm d = mm Velocity is the peripheral surface velocity of the rotating shaft equal to:-

n V = π × d ×  60000

Frictional heating, ambient operating temperature and material conductivity influence the performance of an X-Lube® bush. The maximum permissable PV for a material may need to take these factors into account in order to determine the PV that will give a satisfactory performance.

m/sec

where: d = mm n = rpm W (load)

Maximum PV Values The maximum PV values for an X-Lube® bush are given in the graph at right for lubricated and unlubricated conditions. The values shown are for operation at 20°C room temperature and a relative humidity of 50%. For operation in other conditions, eg. elevated temperature or intermittent operation, correction factors will need to be applied to the PV value obtained from the graph.

X-Lube® bushes made from other plastic materials will have a different PV value. Visit www.xlube.info for more information.

X-LUBE® BUSHES

specification Benefits and Properties

The extensive range of plastic bushes are manufactured and marketed under the trade-name X-Lube®. These bushes are

■

designed to provide an extremely cost-effective alternative to

■

traditional metal bearings, and are injection-moulded using

■

specialised precision tooling. X-Lube® bushes are available

■

throughout Australasia.

■

X-Lube® bushes use a superior polyamide material (nylon 6)

■ ■

impregnated with molybdenum disulphide (MoS2). This additive lowers friction which helps to reduce the need for lubrica-

■

tion, improves wear resistance and increases the life of the

■

bush.

Unsuitable Applications

These bushes have generally been designed with an interference fit on the OD to allow for a good push-fit into the hous-

■

ing. An additional clearance has also been allowed in the ID

■ ■

so that, when the bush is installed, it will have the correct

■

correct fitting and clearances of X-Lube® bushes. Factors such as material type, temperature variation, working environment and humidity may mean additional clearance is necessary. ■

and need to be machined to finished dimensions. Wellequipped machine shops offer efficient, fast production of these specialised bushes before delivery. Where a standard X-Lube® bush is not available or loads, speeds and higher temperatures are outside its capabilities, a specialised bush can be custom-made to suit that application. Visit www.xlube.info for more details.

X-LUBE® BUSHES www.xlube.info

Grease or lubricants will lessen friction and heat generation and increase load bearing capabilities. MoS2 grease should not be used.

Non-standard Sizing

X-Lube® bushes are available in plain (P) or shouldered (S) configuration. Items marked * have a heavy-wall thickness

Operating temperatures above 100°C Surface speed exceeds 8m/sec Total load exceeds 10N/mm2

Additional Lubrication

running clearance. It is important to access www.xlube.info if in doubt about the

Economical and very cost-effective Lightweight compared to metal Easy to install and maintain Superior chemical resistance Self-lubricating Low friction Non-corrosive and resistant to a large range of chemicals and fluids Excellent noise and vibration resistance Good insulation properties

If the X-Lube® bush is not in the standard size range, small quantities are able to be machined from available rod stock. For larger quantities (500 +), it may be economical to injection-mould custom sizes.
