said lubricant container body includes a recess or through hole for receiving a lubricant delivery device of a vacuum pump, said recess or through hole being at least partially surrounded by a collar extending from said lubricant container body;
A lubricant supply system characterized by: the collar completely surrounds the recess or the through hole;
2. A lubricant delivery system according to claim 1. (i) the lubricant container body comprises a porous material; and/or
(ii) said collar comprises a porous material in fluid communication with said lubricant container body;
3. Lubricant supply system according to claim 1 or 2. at least one lubricant return member extending from the lubricant container body for returning lubricant;
Lubricant supply system according to any one of claims 1 to 3. said collar extends more than 1 mm and less than 20 mm, preferably more than 1 mm and less than 10 mm, most preferably more than 2 mm and less than 6 mm,
Lubricant supply system according to any one of claims 1 to 3. the collar extends less from the lubricant container body than the lubricant return member;
5. Lubricant supply system according to claim 4. a contactor engaging said lubricant transfer device for transferring lubricant from said reservoir to said lubricant transfer device, said contactor optionally extending radially into a recess or through-bore; made of lubricating material, preferably integrally with the lubricant container body,
Lubricant supply system according to any one of claims 1 to 4. The lubricant container body (i) has an annular shape, preferably the recess or through hole is centrally located, and/or (ii) has a second major surface opposite the first major surface. wherein the collar extends from the first major surface, the recess is defined in the first major surface, or the through hole extends from the first major surface to the second major surface. extending across the face,
Lubricant supply system according to any one of claims 1 to 7. said collar is made of flat elements, preferably by rolling up
Lubricant supply system according to any one of claims 1 to 8. Said collar is connected to a plurality of strip elements extending radially from said collar, and optionally (i) said strip elements are preferably partially stripped of said flat element prior to rolling up said flat element. and/or (ii) the strip element is connected to the first major surface for fluidly connecting the lubricant container body and the collar.
Lubricant supply system according to any one of claims 1 to 9. said lubricant container body being at least partially surrounded by said housing, said collar extending from said housing, optionally (i) said collar being connected to said housing by at least one web; and /or (ii) said housing includes at least one ring element surrounding and supporting said collar, said ring element being connected to said housing by at least one web, said lubricant container body optionally comprising: , a first major surface and an opposite second major surface, the ring element being disposed on the first major surface of the lubricant container body;
Lubricant supply system according to any one of claims 1 to 10. A vacuum pump, in particular a turbomolecular pump,

13. Vacuum pump according to claim 12. the collar is out of contact with the rolling bearing and/or out of contact with the lubricant transfer device;
14. Vacuum pump according to claim 12 or 13. Preferably, a method for manufacturing a lubricant supply system according to any one of claims 1 to 11,
providing a flat element;
cutting the planar element to provide a plurality of partial cuts, such that an uncut portion of the planar element has a width corresponding to the height of the collar;
providing a housing;
rolling up the flat element;
inserting the rolled flat element into the housing until the uncut portion extends from the housing to form a collar extending from the housing;
radially bending the cut portion of the flat element to form a strip element;
providing and inserting a lubricant container body into the housing;
