Disclosed is an electric cutting machine comprising: a base (1); a longitudinally movable table (2); a cutting head (3) provided with a cutting disc (32) and an electric drive motor (33); two rolling assemblies (4) with wheels (41) and rolling bearings (43) mounted by means of independent axles (42, 44) on a vertical partition (52) of parallel longitudinal profiles (5) mounted on the base (1); a pair of longitudinal guides (6) attached to the movable table (2) and which comprise a longitudinal support track (63) for supporting on the wheels (41) of the corresponding rolling assembly (4), and a horizontal wing (65) located under the rolling bearings (43) of the corresponding rolling assembly (4); and interchangeable longitudinal guides (6a) longer than the longitudinal guides (6), for adapting the cutting capacity.

A bearing unit for a marble cutting machine has a radially outer ring, rotatable with respect to an axis of rotation (X) and is provided with a radially outer flange portion. Additionally, the bearing unit is provided with a stationary radially inner ring with a through hole in which the ratio between a dimension of an internal diameter (D) of the through hole and a dimension of the axial thickness (T) of the radially inner ring is between about 6.7 and about 11.1. A row of rolling bodies is interposed between the radially outer ring and the radially inner ring. A sealing shield is made of composite material and interposed between the radially inner ring and the radially outer ring, rotatable with respect to the rotation axis (X) and steadily anchored to the radially outer ring. The shield is provided with a sensor molded in it.

A bearing adapter for a disk-shaped accessory tool which has two sides. The bearing adapter includes a bearing unit configured to reduce a bearing recess of the accessory tool. The bearing unit is configured to adjoin the accessory tool and to enclose a portion of the accessory tool on the two sides when the bearing unit is mounted on the accessory tool.

A telescoping tool includes a pole assembly, a driveshaft, a plurality of bearings, and at least one connection member. The pole assembly includes an outer pole and an inner pole. The inner pole is slidably received in the outer pole. The pole assembly is movable between a retracted configuration and an extended configuration. The driveshaft extends longitudinally in the outer pole and the inner pole. Each bearing of the plurality of bearings includes a driveshaft passage defined therein. The driveshaft passage receives the driveshaft therethrough. Each bearing further includes an end connection passage defined therein. The at least one connection member joins adjacent bearings of the plurality of bearings. The at least one connection member is disposed in the end connection passage of each of the adjacent bearings.

A table saw includes a table assembly having a top surface, a cutting assembly, and an adjustment assembly. The cutting assembly is arranged below the table assembly and is movable relative to the top surface. The adjustment assembly is operably connected to the cutting assembly and includes an input member, an output member, and a flexible shaft. The output member is operably connected to the cutting assembly and is configured such that rotation of the output member causes the cutting assembly to move relative to the table top surface. The flexible shaft has a nonlinear central axis, a first end operably connected to the input member, and a second end operably connected to the output member. The flexible shaft is configured such that rotation of the input member causes rotation of the first and second ends, and rotation of the second end causes rotation of the output member.

A scribe saw head assembly is provided for a loin puller and has substantially reduced wear and increased life of the assembly components. A pinion assembly includes a pinion shaft and a thrust bearing. The shaft has a flange to support the thrust bearing, which is retained by a pair of retainers. The flange and thrust bearing provides constant contact between the pinion shaft and the standard of the scribe saw assembly, prevents side to side movement of the pinion shaft, and prevents longitudinal floating of the pinion shaft.
