Today’s sport compact race engines make more power than ever before. Yesterday’s engine bearings’ load capacity no longer works for today’s sport compact race engines. Tomorrow’s engines will be even more powerful.

King bearings meet these demands with higher performance benchmarks, advanced materials and unique geometrical features.
King Racing’s SV, GPC, XP, and XPC series of rod and main bearings were developed to meet these challenges through technologically advanced geometrical features and a unique metal structures. Together, they drive the industry to a higher level of durability, performance and expectation.

pMax Black is a unique tri-metal structure the has been developed to meet the ongoing demand for bearings with increased load capacity. As engines evolve and gain more power, engine bearings have to be able to handle the extra loading.

pMax Black consists of three layers that come together to form the strongest tri-metal bearing in the industry with load capacity exceeding the competition by as much as 24%. King Racing’s new hardening technology modifies the overlay molecular structure and creates a fatigue resisting shield.

The intermediate layer of a typical race bearing contains 2-3% tin, with hardness values of 90-95 HV. For a superior pMax Black intermediate layer, we increased the tin content to 4.5%, making it 22% harder (115 HV), with a load carrying capacity of 17,000 psi.

The overlay of a typical high performance bearing consists of a leaded alloy that contains 2-3% copper. It achieves a hardness level of 11 – 14 HV, and a maximum load capacity of 8,000-8,500 psi. King’s pMaxBlack overlay is significantly stronger than conventional overlays due to its 5% copper content and an innovative nano-scaled hardening process.

The pMaxBlack overlay contains 5% copper. It is further strengthened by a proprietary nano-scaled hardening process that modifies the molecular structure and creates a black fatigue-resistant shield. The outcome is a significant 29% increase in overlay hardness (18.1HV) and overall 24% increase in load capacity (10,200 psi).

SecureBond – Maximum tri-metal structural integrity

High loads and high RPM’s create critical stresses that travel through the multi-layer construction of a tri-metal race bearing. SecureBond is a micro-etch surface preparation process that strengthens the tri-metal structural integrity. SecureBond reduces the likelihood of catastrophic failure due to delamination of one layer from the other under extreme load conditions or metal–to-metal contact.

Heavy marble base and solid rod holder.
Color: White-aa, Color: White-aa
After researching the many different marble base towel holders, which is what I wanted to match my marble decor, I finally settled on this which arrived today, packed very nicely in a Styrofoam tight box to protect the marble and came with it as you can see a gift of some very soft Microfiber dish cloths, which work very well at removing smudge marks on kitchen appliances. It took me 30 seconds to join the base to the rod. It came with a little tool to tighten the base however it really wasn’t necessary. I then covered the hole under the base with a piece of One-sided circular sticky, felt, which covered the hole very nicely. I have tried it, and it does do as it says, and the marble base is heavy enough where it holds the roll of paper towels so that with a couple of tugs, I can get one of the perforated sections out. Does take more than one tug as some people showed but two tugs or three light ones really doesn’t matter it gets the job done and in a far lower price than any of the others, in fact, some of the recommended others were 2 1/2 times more expensive and the reviews were not good at all. It pays to take the time to go through people’s reviews like mine and that’s why I believe in completing the reviews whenever I can time permitting. I’m giving this a five star and I think that you will too. I was lucky based on some of the other marble bases that were shown for this product that I got a significant amount of gray marbling matter because some of them had very little it’s just the way the marble runs and you take your chance, but I was lucky.

Base a bit light

Nice touch!
Color: Gold-b, Color: Gold-b
Handles large paper towel rolls. The gold color on the top which is mainly what you see when you have paper towels on it, coordinates nicely with the various shades of gold in my kitchen. The 4" pulls brushed gold, the Delta pull down facet as well as the Euro (Lamps plus) aged brass mini pendant. I find it easy to tear off paper towels even without the small tear bar found on different holders. Was a few $ more but it matches perfectly. Well worth it.
