Oilless Wear Plate [Overview]
Slide Components■Features(1) The wear plates can be used without lubrication.
A lubricating system can be completely abolished,assembly time can be reduced, oil pollution can beeliminated, environment can be maintained clean andcosts can be reduced.
(2) The wear plates are excellent in "friction resistance"and "self-lubrication".
There is no "scoring" or "seizure" under harshconditions.
(3) Various standard part sizes are available, considering
design standard of customer.

copper based powder and graphite,
occurrence of seizure is very limited.

Since the surface hardness is HRC40 or
more, it is excellent in wear resistance.

TSP

Since the surface hardness is HRC58 or
more, it is exceptional in wear resistance.

(1) When adjusting the thickness of the plate, please machine on the back surface only.
(2) As the sintered surface is weaker against shocks than casted steel surface, please be mindful sosintered surface does not get damaged.
(3) If the sintered surface must be machined, it should be done within a Ra1.6 surface finish as the lifeof this product depends on the surface finish. Also, be mindful to inspect the surface so there are nosharp edges or burrs at the corners.
(4) Always make sure that there are no metal chips and/or debris on the sintered surface after machining
the product.
(5) There will always be small porosity in the sintered surface, even after the product gets well-machined,
as it s mentioned in the Product Quality section. Please consult us regarding our quality standard
with the porosity level of the sintered surface of this product. If the size of the porosity you areexperiencing is within the standard, there should not be any problems. If you are not sure of the levelof the porosity you are experiencing, please contact us.
(6) Lubricant is present in the sintered material. If lubricant is lost due to machining, add lubricant to theproduct. Addition of lubricant should be done with No. 32 industrial lubricant for 24 hours prior to use.
(7) Please put some lithium-based grease on the sliding surface during assembly or after maintenance for
initial start-up.

10Features(1) The sliding surface becomes black or black gray after operation due to the film of special solidlubricant. This is normal, do not remove film by wiping.
(2) When dies are in use, make sure that there is no foreign matter such as metal chips or dirt on the sliding
surface.
(3) Apply a small amount of lubricant for initial lubrication in die spotting.
(4) When a die is reused after storage for a long time, the sliding surface may have rust. Clean the sliding
surface and apply lubricant to the surface.
(5) If products are additionally machined, do not damage the surface. Chamfer corners so that sharp edges orburrs are not present.
(6) There may be insufficient fastening force with the bolts due to an unbalanced load, which may result infailure of the bolts. It is highly recommended that the wear plate is backed up.

Base Metal■For Operation

SlideComponents

Sankyo's wear plates for press tooling are manufactured
with an appropriate pattern of embedded special solid
lubricant on metal base plates.
Its function is that the base plate supports load and that theembedded special solid lubricant provides self-lubrication. It
provides excellent durability without lubrication under harshconditions.
