Abstract: A bearing including: a sidewall including a substrate and a low friction layer overlying the substrate, where the sidewall further includes: an unformed section; at least one slot in the unformed section; and at least one protrusion extending from the unformed section forming a generally concave or convex cross-sectional shape in the sidewall.

Abstract: The subject application relates to a cupseal for a compressor and method for preparing the same. Systems and methods are disclosed that include providing an annular seal for a compressor. The annular seal includes a substantially planar first portion, a first angled portion extending at an angle from the substantially planar first portion, and a second angled portion extending radially at an angle from the first angled portion. The annular seal is formed from a fluorinated polymer and includes at least one additive or filler. The annular seal exhibits reduced wear and an increased lifespan.

Abstract: A bearing article can include a metal substrate having a bronze layer; a PEEK layer; a PTFE composition layer overlying and penetrating the PEEK layer. A method for preparing a bearing article can include providing a metal substrate with a sintered bronze layer, electrostatic spraying a non-fluorinated polymer onto the metal substrate followed by spraying a fluorinated polymer onto the non-fluorinated polymer and heat rolling to form a laminate.

Abstract: A laminate article can include a substrate and a layer of a heterogeneous mixture of a non-fluorinated polymer compound and a fluorinated polymer compound. The laminate article can include a gradual concentration gradient along an axis perpendicular to the substrate. The gradual concentration gradient can include the change of the amount of the non-fluorinated polymer and the fluorinated polymer compound relative to the axis perpendicular to the substrate. The layer can further include at least one filler. The laminate can be applied as a bearing material.

Abstract: A maintenance-free and self-lubricant slide bearing comprising a metal support, an intermediate adhesive layer applied directly thereto and a sliding layer based on UHMWPE. The bearing laminate is characterized by a high peel-strength and does not require a surface pre-treatment of the metal support to achieve a strong bonding of the UHMWPE sliding layer to the metal support. The preferred adhesive in the intermediate layer is an anhydride-grafted polyethylene. The invention further includes a process of making the bearing laminate.
