Abstract: A gripper block for conveying continuous rod in a well bore comprises a carrier body formed of a first metal and arranged to be mounted on one of the pair of continuous drive chains of a continuous rod conveying apparatus. A gripping element supported on the carrier body is arranged to engage the continuous rod and is readily separable from the carrier body. The gripping element is formed of a second metal which is softer than the first metal of the carrier body and softer than the continuous rod.

Abstract: A bearing assembly comprises a shaft having a longitudinal axis, a sleeve supported concentrically about the shaft, and a tubular liner received between the shaft and the sleeve so as to be concentric therewith and so as to support the sleeve for rotation relative to the shaft. The tubular liner comprises synthetic fibres woven helically about the longitudinal axis of the shaft and a rigid surrounding material which surrounds the synthetic fibres. The sleeve also comprises synthetic fibres woven about the longitudinal axis of the shaft and a rigid surrounding material which surrounds the synthetic fibres. The synthetic fibres may comprise glass fibres, polyester fibres, para-aramids, and/or Polytetrafluoroethylene fibres which are wound helically about the longitudinal axis. The surrounding material may comprise a thermoset material, a phenolic material, an epoxy, and/or a resin which is set to be rigid about the fibres.
