HK series is designed for heavy load occasions. It is equipped with high-strength cage design, which can withstand extreme load and high speed. HD series, with its innovative fractured outer ring design, enables the radial deep groove ball bearing to set the maximum steel ball parameters, greatly improving the dynamic load capacity of the bearing and extending its service life. The HA series is an indivisible design, its outer ring is provided with a counterbore, and a monolithic high-strength cage is arranged between the rollers. This series is ideal for preload and/or thrust applications. At the same time, Timken specially designs deep groove outer ring and modified inner ring for ultra-high speed applications. The HT series with excellent performance is characterized by a complete deep groove outer ring, a single piece of high-strength cage and two ultra deep groove inner rings, which are widely used on high-speed shafts with forward and reverse thrust loads.

Timken (NYSE: TKR) announced that it will provide bearing solutions for the largest slag vertical mill in China. The diameter of slag vertical mill disc of this specification is 5.7m, which is developed and manufactured by CITIC Heavy Industry Machinery Co., Ltd. (hereinafter referred to as “CITIC Heavy Industry”), a leading domestic cement production equipment manufacturer [2].

Slag vertical mill plays an important role in the construction of large-scale infrastructure in China and contributes to the sustainable development. Slag is the residue of ore after benefaction or smelting. After vertical grinding, it can be used as the active mixing material of cement to produce high-performance concrete, which is widely used in roads, bridges and other infrastructure projects. This time, the slag vertical mill independently developed by CITIC Heavy Industry can produce up to 1.2 million tons of slag powder annually.

“Many large-scale construction projects are being carried out all over China, which has greatly stimulated the demand for high-performance concrete.” Mr. Feng Shilong, president of Timken China, said, “Timken has always maintained close business relations with CITIC Heavy Industry and other customers in this field to ensure that they can meet their customers’ growing demand for concrete and other building materials. The success of this business is a strong proof of the joint efforts and innovation of our two company teams.”

This time Timken provided a combined solution of tapered roller bearing and cylindrical roller bearing products for the LGMS5725 slag vertical mill manufactured by CITIC Heavy Industry. Mr. Ruan Chunhao, General Manager of Timken’s Processing Equipment Industry Business Unit in China, further pointed out that Timken’s pursuit of innovation and deep understanding of CITIC Heavy Industry’s product installation needs are the key to the success of this business.

“For example, TimkenDuraSpexx ™ Bearings can better meet customer needs, because DuraSpexx ™ The bearing adopts reinforced materials and has a specially designed roller profile; Moreover, the technical experts of Timken also suggested that the spacer should be grind-ed by CITIC Heavy Industry itself, so as to achieve better performance in the installation phase, “said Mr. Ruan Chunhao.” In the recent order, the basic materials of the product have been further improved, so as to help customers to further save costs and enhance competitiveness on the basis of meeting or even exceeding the product application performance standards. ”

Timken provides customers in the cement industry with a full range of friction management and mechanical power transmission solutions. A series of bearing products such as tapered roller bearings, self-aligning roller bearings and cylindrical roller bearings produced by Timken are widely used in cement vertical mills and other key equipment in the cement industry worldwide.
