Grease Nipples

Hydraulic-type Grease Nipples

Hydraulic-type%20Grease%20Nipples

 

Application Area 

 

Rama Steel Products hydraulic-type nipples are suitable for all standard lubrication points, which have to be frequently lubricated in a reliably way. Due to their multi-purpose field of application, they are the most commonly used types of grease nipples.

 

 

Versions

 

In general, our hydraulic-type grease nipples according to DIN are made of steel, case-hardened, zinc-plated and passivated, and they are featured with a tapered thread. The head diameter is 6.5 (-0.2) mm /0.256" - 0.008". For safety reasons and in order to avoid abrasion wear, the standard demands 550 HV as a minimum for a surface hardness. Therefore, we operate this decisive process in our own curing oven. We offer various standard types also in brass or stainless steel V2A/V4A. Of course, our hydraulic-type nipples are also available in different angle versions, with a self-forming thread, or as drive-in type.

 

 

Special Versions

 

Upon request, Rama Steel Products manufactures hydraulic-type nipples in other versions, with respect to e. g.

  • dimension
  • material
  • thread size
  • thread form (e. g. with cylindrical thread)
  • different opening pressure
  • surface colour (e. g. yellow passivated)
  • further surface treatment
  • unhardened
  • etc.

 

 

Mounting Instructions:

 

In order to allow for a proper lubrication with all common grease guns, the head space, which is necessary for installation, should be considered (please see table with dimensions).


 

 

Operating Instructions:

 

As suitable lubricating nozzle, we recommend our hydraulic couplers.

Grease Nipples - Stainless Steel

Grease%20Nipples%20-%20Stainless%20Steel

Please find hereafter a selection of our grease nipples which we provide in the galvanized steel
variant, in brass and also - as standard - in stainless steel.

The stainless steel grades we most commonly use are 1.4305 = 303 (V2A) and 1.4404 = 316L (V4A). Other
models and materials can, of course, be supplied. Do ask us about the types wanted and sizes !

What is the origin of the "V2A steel" and "V4A steel" names?

    V2A Steel came about in the German Krupp steel works in 1912 as "Versuchs (test) smelt 2
Austenite" and has remained to this day as the most usual designation in Germany.
    V4A also arose there as "Versuchs (test) smelt 4 Austenite" and continues to be known of under
this test heading.

Austenite is the name for a chrome/nickel steel which cannot be hardened by heat treatment and is, as
a rule, non-magnetiseable.

In particular, more and more enquiries are being made about V4A stainless steel. What makes this
material so special ?

    In contrast to SST303 (V2A), SST316L (V4A) steel - 1.4404 is additionally alloyed with 2 -2.5 %
of molybdenum (Mo). This makes the steel that much more resistant to corrosion - especially in media
containing chloride (seawater, swimming baths, chemical industry, etc.). In addition, its exceptional
longevity ensures that the material is used in a highly cost-effective manner.
