Small to midsize OEMs that now source rotating-equipment products and services through multiple vendors may want to consider using a dedicated, local distributor. Distributors have access to a broad product range and can readily supply related items such as bearings, electric motors, belts, and gearboxes. This simple tactic of consolidating your supply source will immediately provide tangible benefits, including one-stop shopping, a single point of accountability, and the preferred services that often come from a close OEM/distributor business relationship. Moreover, distributors can bring the expertise of their suppliers to your organization, including advanced engineering services, ranging from applications engineering, failure and design-life testing, CAD, and vibration/reliability specifications, as well as assembly and warranty information Case in point: A small OEM that builds rope sheaves used in paper-mill dryer sections had recently changed a bearing spec from two single-row, deep-groove ball bearings to a double-row, angular-contact ball bearing. The update looked great on paper, but end users were reporting a significantly shorter bearing service life. The OEM’s distributor brought in SKF to help solve the problem. SKF engineers reviewed the rope-sheave design with computer programs specifically made to analyze bearing operating temperature, loads, raceway positions, and failure modes. The resulting calculations…

There have a new bearing steel GCr9 appeared in the market,which supplying for Turkey, Poland and some other Europe countries after-market, let’s get the details of what material as below. From the bearing appearance, there is no difference between GCR9 and GCR15, but for the product performance, there have obvious difference. From the bearing appearance, there is no difference between GCR9 and GCR15, but for the product performance, there have obvious difference. Due to the difference of Cr element content, GCr15 have a better performance of wear resistance than GCr9, usually bearing of GCr15 material working life will be longer. . DANA and TBB have a project of needle roller bearing which applied for hydraulic motor. DANA technical and engineer person have inspected TBB Changzhou factory twice on Feb-26th and last December , and our factory satisfied their high quality OE market requests. . . The bearing world has become quite different in 2018 with the introduction of tariffs, price increase of steel in China, closure of factories due to environment issue and also sudden demand increase. Even though the demand levels have now come back to normal with the easing of steel supply as compared to before the cost…

●What is PPAP? PPAP is the abbreviation of Production Part Approval Process, a valuable tool for establishing confidence in component suppliers and their production processes. Initially, PPAP was utilized by the automotive and aerospace industries. PPAP is now being utilized by several industries to improve communication and provide quality products. Within the automotive industry, the ultimate resource for PPAP information is the manual published by the Automotive Industry Action Group (AIAG). PPAP defines the approval process for new or revised parts, or parts produced from new or significantly revised production methods.?It verifies that the supplier understands all customer engineering design specifications and requirements and that the process is capable of consistently producing product meeting those requirements during an actual production run at the quoted production rate. ●How to perform PPAP? The PPAP process consists of 18 elements that may be required for approval of production level parts. Not all of the elements are required for every submission. There are five generally accepted PPAP submission levels. A, 18 elements of PPAP: 1. Design RecordsA copy of the drawing. If the customer is responsible for designing, this is a copy of customer drawing that is sent together with the Purchase Order (PO)….
