Bleed lubrication for linear motion slides
30 January 2012
Now available as an option on all its core linear motion products is the HepcoMotion Bleed Lubrication System, providing constant lubrication to the slide vee face via specially machined pathways, connected to an external supply via lubrication inserts. Lubrication is delivered directly to the vee face and, in turn, it is picked up by the carriage and bearings as they pass over each lubrication exit point. In this way lubricant is carried around the entire system, ensuring an even distribution.
The system saves on the number of lubricators or cap seals normally fitted to each carriage, thereby reducing system friction and associated cost, as it is the slide that is responsible for delivering the lubricant to where it is needed. These components do still play a vital role however, so it is recommended that one in four carriages are fitted with lubricators or cap seals in any system, where bleed lubrication is being used.
Slide lubrication inserts are available with either an M5 thread or 4mm diameter bore with O-ring seal to accord with the chosen linear system. Lubricant can be supplied via a grease- or oil-filled pressurised canister that dispenses lubricant at a controlled rate, or via the customer’s own centralised lubrication system.
HepcoMotion Bleed Lubrication can be specified on the GV3 precision slides, HDS2 heavy duty slide system, PRT2 ring and track system, SL2 stainless steel and corrosion resistant range and also the DTS driven track system. In addition to slides with dual bleed lubrication holes, double edge slides are also available with single bleed lubrication holes. These can be positioned on either vee and anywhere along the length to suit the application. Single edge slides can also be supplied with the bleed lubrication facility. Both double and single edge slides are provided with a range of dedicated inserts.
